Andrew Webb wins Huibregtsen Award for Affordable MRI Scanners

High field MRI expert, Professor Andrew Webb of the Microelectronics department, and his Ugandan collaborator, Johnes Obungoloch, have been awarded the 2023 Huibregtsen Prize. Their notable achievement is the creation of an affordable, portable, and long-lasting MRI device tailored for brain imaging in developing nations.

Webb's team introduced a 'low-field MRI scanner' that boasts ease of transportation, maintenance, and ecological sustainability. Ever better, Webb’s new device is priced at just 1% of the typical MRI system. The brain scans generated by their MRI are instrumental in diagnosing curable diseases in underdeveloped regions, with the first model already operational in Uganda.

Highlighting its distinctive nature, the jury commended the initiative for merging top-tier technology development with suitability for developing regions. They also lauded the emphasis on knowledge dissemination and instruction.

The Huibregtsen Prize, founded in 2005 by The Evening of Science & Society Foundation board, is an annual award recognizing pioneering research projects with profound societal implications.
The accolade was handed over by the departing Minister of Education, Culture, and Science, Robbert Dijkgraaf, on 9 October at Pieterskerk, Leiden. Professor Webb was granted a €25,000 check and a bronze artwork from Wil van der Laan. Meanwhile, Obungoloch tuned into the event via a live stream from Uganda. In addition to the monetary prize and artwork, the duo also earned a workshop at the Lorentz Center in Leiden.

2022 4TU.NIRICT Community Day, November 14

Identified are 3 themes around which we would like to bring NIRICT researchers together to discuss and to explore per theme the opportunities for interdisciplinary collaboration. The themes are related to the societal challenges we are currently facing and require interdisciplinary effort in order to be addressed effectively. We believe that productive discussions during the event could be instrumental in forming new research lines, but also project consortia around various national R&D investment programs addressing the knowledge and innovation agenda’s (KIAs) of the Netherlands (

Themes of the day:
• Health and ICT People live longer, more healthcare is needed. Work pressure in healthcare is rapidly increasing. More data is collected by smart devices. How can the ICT community contribute solutions to keep our society healthy?
• Energy and ICT The current explosion of the energy prices shows that we are facing an unstable situation with respect to energy production and consumption. We produce more solar energy on one hand and consume more energy due to air conditioners and electric cars. We need smart solutions both in production and consumption. Moreover, due to its significant share in energy consumption, ICT systems from the end user devices to power-hungry data centers need to become more energy efficient.
• Agriculture and ICT We just had another summer with extreme heat waves and droughts. The climate changes we are facing have tremendous consequences for agriculture. The population is growing and the pressure on nature is increasing. What smart solutions do we see to deal with the challenges to keep our planet healthy and at the same time to keep the food production in line with the population growth?
The Community Day starts at 12:30hrs with a walk-in lunch. At 13:30hrs the official part will start with a number of short presentations, followed by several parallel sessions regarding the three themes of the day. You can indicate your preference on the registration form. Afterwards there will be a networking drink from 17:00-18:00hrs.

It would be great to welcome many of you on November 14th, because together we strengthen the ICT community of The Netherlands, so join us for the 4TU.NIRICT Community Day 2022, November 14, in Van der Valk Hotel Utrecht and register here by November 6, 2022.
Your data will only be used for registration and will be discarded within one week after the 4TU.NIRICT Community Day. If you have any questions, don’t hesitate to contact us:

Gravity grant awarded to research on brain interactions

The goal of this research is to develop principles, devices and methods to take these interactions into account and thus understand more about brain disorders, as well as moods, emotions and compulsions.

The research project is called 'The Dutch Brain Interfaces Initiative' and is led by researchers from Radboud University Nijmegen. TU Delft will contribute to the development of computer models, and microfabrication technology for the development and validation of closed-loop control for neural prostheses. These prostheses can give us back lost senses and control, enabling us to bypass injuries and treat an unprecedented range of brain disorders, restoring a better quality of life for deaf, blind, paralyzed and mentally ill people. 

Ultimate applications of the multi-year research include the use of Deep Brain Stimulation on patients with motor and psychiatric disorders, the development of Brain-Computer interfaces that enable communication for people who cannot speak and the deployment of visual implants for the visually impaired and blind. Frans van der Helm and Wouter Serdijn are the leaders of the Delft research project. Frans van der Helm: 'The human brain is the ultimate technical challenge for engineers. It is great to be able to use our technical background and technical capabilities to contribute to a better understanding of, and better interaction with, the human brain.'

The Dutch Brain Interfaces Initiative is the combination of a platform with computer, software and hardware elements, aimed at facilitating closed-loop manipulations in the long term, and brain monitoring in a naturalistic environment, with a neuroscience research program with 3 main objectives: to increase the understanding of the general principles of brain dynamics, to develop strategies to influence, restore or improve those dynamics and the cognitive function they support, and to understand the neural basis of behavior under naturalistic conditions.

Project proposal UPSIDE, successful in the EU call EIC Pathfinder challenge

The multi-disciplinary and international consortium led by Dr. Tiago Costa, includes ME department PIs Dr. Dante Muratore and Prof. Dr. Ir. Wouter Serdijn, and partners from Belgium, Germany, Italy, Portugal, and the USA. With a total budget of 4.2 M€, the consortium will use the combined expertise in bioelectronics, brain-machine interfaces, focused ultrasound, neurobiology, neurosurgery, and psychiatry to achieve a technological breakthrough towards a personalized treatment for depression.

Project description:

Major depressive disorder (MDD) is the leading cause of disability worldwide, affecting 300 million people with a lifetime prevalence of 15%. Approximately one third of all MDD patients fail to respond to currently established treatments based on medication and psychotherapy, thus falling into the category of Treatment-Resistant Depression (TRD) patients. Electroconvulsive therapy (ECT), repetitive Transcranial Magnetic Stimulation (tRMS), Vagus nerve stimulation, deep brain stimulation (DBS) and transcranial focused ultrasound (tFUS) still show poor spatial resolution (ECT, tRMS, tFUS) or low network coverage (VNS, DBS), with average remission rates in clinical trials still lower than 30 %. Apart from the existing stimulation hurdles, reliable biomarkers for depression are needed as a diagnostic tool, and, in the case of neuromodulation-based treatments, to determine the stimulation efficacy and allow for personalized treatment. The UPSIDE project aims to overcome the limitations above by developing a hybrid epidural brain interface (EBI) for high-precision ultrasound neuromodulation (eFUS) and high-fidelity neural recording (eREC) for the personalized treatment of depression.

Happy Secretaries Day!!!

Our congratulations and best wishes!

TU Delft start wereldwijd onderzoek naar oorsuizen (tinnitus)

Wereldwijd onderzoek naar oorsuizen (tinnitus)

Veel mensen hebben last van een continu geluid in hun hoofd. Tinnitus heet dat. Omdat er eigenlijk nog te weinig bekend is over de oorzaken, is er een wereldwijd onderzoek gestart onder de noemer ‘Tinnitus House’. De hoop is dat er uiteindelijk een remedie wordt gevonden.

Tinnitus wordt ook wel oorsuizen genoemd. Al is die laatste omschrijving een understatement, want de geluiden die sommige mensen horen zijn vergelijkbaar met een vrachttrein die door je hoofd raast. Tinnitus hoor je in een stille ruimte, maar ook met oordoppen op. Dan lijkt het alsof er toch geluid is, maar die waarneming komt van binnenuit. Die geluiden heb je in alle vormen: van zacht tot hard, van hoog tot laag, van continu tot af en toe, in één oor of in beide oren.

Eén op de drie volwassenen ervaart in het dagelijks leven wel eens een duidelijke toon in een oor gedurende een aantal seconden. Ook de zogeheten ‘disco-tinnitus’ is je wellicht bekend: als je oren een tijdlang zijn blootgesteld aan veel lawaai, is er eenmaal in de stilte een ruis of fluittoon te horen in je oren. Uiteindelijk komt hierna gelukkig bij de meeste mensen het gehoorsysteem weer tot rust en dan verdwijnen de geluiden. Echter, veel blootstelling aan harde geluiden kan ertoe leiden dat de ruis of fluittoon permanent te horen blijft.

Overgevoeligheid voor geluid

Heb je last van een van onderstaande vormen van overgevoeligheid voor geluid? Dan kun je ook last hebben van tinnitus.

  • Misofonie. Extreme hekel aan specifieke geluiden, zoals bijvoorbeeld blaffende honden of smakgeluiden.

  • Hyperacusis. Mensen die hieraan lijden zijn overgevoelig voor vaak hoge harde geluiden die als onaangenaam en pijnlijk worden ervaren. Denk aan gillende kinderen, of een alarm dat afgaat.

  • Phonofobie: Hardnekkige, abnormale en niet-realistische angst voor geluid. Deze mensen zijn bang dat normale geluiden hun gehoor beschadigen

Tinnitus is zelden te behandelen

Wat iemand met tinnitus dus hoort, zijn schijngeluiden. Die ontstaan doordat het gehoororgaan of de zenuwbanen – zonder dat er geluiden zijn – signalen doorgeven die in de hersenen de betekenis ‘geluid’ krijgen. Waardoor ontstaat zoiets?

  • Beschadigingen in het laatste gedeelte van het gehoororgaan of veranderingen in de zenuwbanen of hersenen kunnen een oorzaak zijn.
  • Ook spiertjes rond het oor die zich samentrekken of problemen in het middenoor kunnen voor tinnitusklachten zorgen.
  • Andere mogelijke oorzaken zijn afwijkingen aan de bloedvaten in het hoofd en een hoge bloeddruk, die een kloppend of tikkend geluid in het ritme van de hartslag veroorzaken

Tinnitus Retraining Therapy (TRT)

Tinnitus Retraining Therapy (TRT) is één van de weinige wetenschappelijk onderbouwde therapieën voor tinnitus en overgevoeligheid voor geluid. Je leert het hinderlijke geluid van het oorsuizen naar de achtergrond te drukken door het als een normaal geluid te beschouwen waarmee gewoon te leven is. Het maakt gebruik van het feit dat je hersenen ook in staat zijn om bijvoorbeeld het zoemende geluid van een koelkast te negeren.

Deze therapie wordt onder andere aangeboden bij audiciens als Beter Horen en Schoonenberg Hoorsupport.

Gehoorverlies bij tinnitus

Naast de irritante geluiden hoort bij tinnitus ook vaak gehoorverlies. En nog vervelender: tinnitus is helaas zelden te behandelen met geneesmiddelen of een medische ingreep. Klachten kunnen wel wat worden verminderd door de aandacht voor de geluiden in het hoofd te verplaatsen naar bijvoorbeeld andere geluiden.

Hoortoestel met tinnitusmaskering

Er zijn hoortoestellen op de markt die een ruis of andere prettige geluiden genereren, zoals bijvoorbeeld geruis van de zee. Heb je behalve tinnitus ook last van behoorlijk gehoorverlies boven een bepaalde waarde (de audicien kan dit meten), dan kan dit een uitkomst zijn. Een nadeel van de maskering, is dat je hierdoor niet went aan je eigen tinnitusgeluid.

Wereldwijd tinnitusonderzoek

Omdat er eigenlijk nog te weinig bekend is over tinnitus is er een wereldwijd onderzoek gestart onder de noemer ‘Tinnitus House’. Dit onderzoek wordt uitgevoerd door de Stichting BrainInnovations onder supervisie van de Technische Universiteit Delft in samenwerking met de Universiteit van Regensburg (Duitsland), Trinity College Dublin (Ierland) en de University of Otago (Nieuw-Zeeland) en mede gefinancierd door de Stichting TinnitusFree. Het doel is om het tinnitusonderzoek een nieuwe dimensie te geven door (big) data-analyse systematisch te testen met klinische trials.

Meewerken aan het onderzoek naar tinnitus?

Heb je last van tinnitus en wil je meewerken aan dit onderzoek? Op de site van Tinnitus House is meer informatie te vinden over tinnitus en over dit onderzoek. Ook kun je je daar abonneren op hun nieuwsbrief.

Meer informatie over tinnitus vind je ook in het boek Eerste hulp bij oorsuizen van Olav Wagenaar.

Heart rhythm expert Natasja de Groot: ‘Every heart is different’

The electrodes in the display cabinet show the technical developments over the last 20 years. The oldest one looks like a kind of small shower head from which four cables emerge, ending in computer mouse-sized plugs. Natasja de Groot used it during her PhD research on heart rhythm disorders in Leiden. The newest electrode is a wafer-thin strip to which three metres of multilayer flat cable are attached to read out the 192 channels simultaneously. The cable was made at TU Delft in the Bioelectronics group of Prof. Wouter Serdijn (Faculty of Electrical Engineering, Mathematics and Computer Science).

Portret series new Medical Delta professors - Wouter Serdijn

For people with heart, nerve and brain disorders, bioelectronic medicine can make a significant difference. Professor Wouter Serdijn works on these tiny devices. He is a professor at TU Delft and, thanks to Medical Delta, now at Erasmus MC as well. "Technical disciplines often use objective measures, while no two people are the same. It is therefore important to include the subjective side in the design."

In the video below, Wouter Serdijn tells about his Medical Delta professorship:


"I have always worked together a lot, but with my appointment in Rotterdam this has become more formalised," says Serdijn. "I now also have the 'right' to walk around there and am part of the information flow. This structure fits in well with how I am used to working. Not starting from existing pigeonholes, but working together at an umbrella level. Medical Delta is a bundle of great people, both technical, medical and clinical-academic. The engineer, medical scientist and therapist form a triangle. Together they can develop what is best for a patient."

How did your interest in the medical field emerge?

"For my graduation project, I worked on hearing aids together with a technology company. I experienced that something that met the technical specifications perfectly, could be totally unpleasant to listen to, and thus collided with the boundaries of the technical domain. Technical disciplines often assume objective measures, while no two people are the same and an individual person will be different tomorrow. It is therefore important to include the subjective side in the design.

How do you contribute to medical science with your knowledge of bioelectronics?

"I do not know exactly how the body works, but I can help measure, examine and control it. I can read and write nerve tracts. One example we are working on is helping people with paralysis regain their posture when sitting or standing and a rudimentary form of walking. This can now be done mainly with a wheelchair or other aids. But I want to know how we can re-energize their own muscles that are still intact but no longer controlled. How can we restore the connection between the brain and muscles? We are about to start clinical trials for this.

I also want to contribute to implantable technology that someone can wear invisibly as much as possible. For example, the so-called cochlear implant. This device enables a deaf person to hear and therefore to develop speech. But these implants still have an external part. You have to take it off when you go swimming or take a shower, for example, and then you don't hear anything anymore. I want to improve that. Though you can engage in conversations with this implant, you cannot listen to music. That can even be a very unpleasant experience. I think that is a shame; not being able to enjoy music is truly a loss. I want to tackle that as well."

How do you see Medical Delta in the future?

"In ten years, Medical Delta will be a scientific plateau. With connections and prestige in The Netherlands, Europe and perhaps the rest of the world. It will be the nerve centre of a lot of activities. The educational component also plays an important role, for example, with the clinical technology degree programme. Very good things and people are already coming out of this and I have high expectations of them. Because science is one part, but training new talent in the combined disciplines, that is the multiplier. Each year, we now have almost a hundred new graduates. They will soon have a greater impact than the Medical Delta professors of today. They are the future."

What is your advice for successful collaboration?

"Stay connected with where you originate from. That is where your value and your strength lies. You have to build a bridge, but stay true to what you are good at. Also, in collaboration, there must be a genuine mutual interest and you must both benefit from it. If you go up to someone and say 'I need this piece of technology from you' or 'this technology needs to go into a patient', it doesn't work. It takes time to understand what is happening on the other side and what the problems are. You also have to find a common language. With me, for example, everything is straight. The components, my diagrams. In biology, everything is curved, for example, cells, tissues and organs. You have to find a way of dealing with it. It is in the shared fascination with the problem that we find each other."

Which other researcher surprised you?

"Multiple researchers, but Chris de Zeeuw of Erasmus MC keeps surprising me. It is an important reason for choosing his department for my second appointment as a professor. He is an inspiring leader. He has great scientific knowledge and knows how to create a group and offer opportunities. He sees the importance of other disciplines for his own and was perhaps generation zero of Medical Delta."

This article is part of a series in which we highlight the nine new Medical Delta professors. Click here for the other portraits that have been published so far. Wouter Serdijn's research contributes to scientific programs, including, including Medical NeuroDelta: Ambulant Neuromonitoring for Prevention and Treatment of Brain Disease and Medical Delta Cardiac Arrhythmia Lab.

Online conference Neural Interfaces and Artificial Senses (NIAS)

Since 1958 when the first pacemaker was implanted in humans, bioelectronics devices have been increasingly used to interface with different types of tissue, monitor and interact with biological activity. During our continuous endeavors to better study sophisticated neuronal systems we have become more capable of diagnosing and treating various disorders. We are currently emerging in an era where bioelectronic devices are becoming smaller, less invasive and safer, which in turn is being paralleled with new therapies for a vast range of neurological and auto-immune diseases. This opens exciting possibilities for the future, from cutting-edge technology for brain-machine-interfaces with unprecedented functionality, artificial organs and augmented senses that can change the way we perceive the world, to a more human way of interactions with robots.

Topics to be covered by the conference: • Bioelectronic devices • Electroceuticals/Bioelectronic medicine • Neuronal interfaces and implantable electronics • Materials at the interface with biology • Neuronal mechanisms and clinical applications • Artificial visual, auditory, olfactory, gustatory and tactile sensory systems.

Ultrasound for microimplants – enabling personalized medicine with wireless charging

Treatment of chronic autoimmune diseases is no longer limited by the expensive drugs and undesirable side effects. Neuromodulation has been shown to be effective in treating diseases such as rheumatoid arthritis, chronic headaches, asthma or Parkinson's disease. To enable the technology for widespread clinical application, researchers at Fraunhofer IZM are developing a new generation of microimplants as part of the EU Moore4Medical project. These highly miniaturized devices have a special feature: the implants can be charged entirely wirelessly using ultrasound waves.

Assistant professor Tiago Lopes da Costa (Bio electronics) receives the ‘early career HFSP research grant’


Cellular communication is mediated by voltage-gated, ligand-gated and mechanosensitive ion channels. Tools for modulating neuronal communication based on focused ultrasound (FUS) were developed to overcome fundamental limitations in optogenetics, combining non-invasive approaches and high spatial resolution without the need for genetic modification of neurons. Yet, little is known about the fundamental mechanisms of how focused ultrasound waves influence the finely tuned interplay of ion channels and lipid bilayers. How does the frequency and intensity of the ultrasound wave affects the lipid bilayer and different types of ion channels? What is the physical mechanism that governs the triggering of ion channel activity? These questions remain unanswered, with existing hypothesis limited by the spatio-temporal resolution of traditional optical, electrophysiology and ultrasound tools, which prohibit observations at the single ion channel level. To answer these questions we hypothesize that, if there would be a way to monitor effects of the FUS on the lipid bilayer and single ion channels with high temporal resolution, one should be able to monitor ultrasound-evoked oscillating current responses informing on ultrasound neuromodulation mechanisms. Hence, the aim of this proposal is to develop a concurrent experimental and computational approach, where state-of-the-art ultrasound and current read-out devices enabling high-bandwidth electrophysiology are matched with computational electrophysiology simulations. This will allow us for the first time to match the frequency of the focused ultrasound with the bandwidth of single ion channel recordings and the length of the computer-based simulations. We will focus our efforts in three aims, where Aim1 will establish the recording systems and simulations using model membranes alone and a mechanosensitive model channel. In Aim2 we will develop a recording platform integrating US-stimulation and high bandwidth recordings in complementary metal-oxide semiconductor (CMOS) technology, extending our efforts on non-mechanosensitive channels. In Aim3, we will combine the gained knowledge from Aims 1 and 2 to focus on mechanosensitive channel that are hypothesized to be involved in neuromodulation.

Webinar: "Lowering the Barrier for Customized Micro Systems in Medical Applications" Dear EUROPRACTICE member, We are delighted to invite you to a webinar organized by EUROPRACTICE together with dedicated to lowering the barrier for customized micro systems in medical applications, which will take place online on March 24, 2021, from 14:00 to 16:00 CET. If you have been following the trends in medical innovations in recent years, you know that microelectronic solutions are revolutionizing the MedTech industry and improving the quality of delivered healthcare and thus patient life tremendously. Whether it is artificial intelligence (AI), augmented reality (AR), or sensing, microelectronic systems play a key role in accelerating these trends in the medical world. For MedTech companies, it is important that microelectronic systems can be customized, but typically this comes at a high cost.

This is where EUROPRACTICE comes in. The consortium lowers the barrier for customized microsystems by providing affordable access to design tools, fabrication services, and training. If you are interested in learning more about how customized microsystems can make the difference for your medical application, then invest 2 hours of your time to learn about EUROPRACTICE and its affordable services. In this webinar, we will particularly zoom in on Application-Specific Integrated Circuits (ASICs) and Photonic Integrated Circuits, and how those can be fabricated and integrated in microsystems for medical applications. The latter will be illustrated by several testimonials/case studies presented by both academia and industry.

INESC MN 2021 Seminar Series - Dr. Tiago Costa, March 5, 16.00 PM

Neurological disorders are the leading cause of disability and the second leading cause of death, worldwide. Still, a paradigm exists in the available therapies: while pharmaceutical drugs are non-invasive but have poor precision and low effectiveness in the long term, therapies based on implantable electrical stimulators have high precision but are also highly invasive, which reduces patient eligibility. For the first time, a minimally invasive and precise neuromodulation modality is emerging through low intensity focused ultrasound (LIFU). However, the hand-held form-factors of existing ultrasound technology, together with its spatial resolution still being 10x lower than implantable electrodes, are hampering advances in both fundamental neuroscience research and the translation to the clinic. In this talk, I will describe my research on stand-alone ultrasonic microchips, by exploring the co-design and integration of CMOS circuits and piezoelectric materials. With massive miniaturization, focused ultrasound can be delivered through more efficient methods (wearable, injectable) while supporting higher ultrasound frequencies towards higher spatial resolution. These advances will contribute to a new generation of ultrasound technology to bring LIFU neuromodulation to the forefront of neuroscience and neurology.

Delft Bioengineering Institute awards Tiago Costa and Massimo Mastrangeli with 20KEUR grants

Dr. Tiago Costa (BE) and Dr. Massimo Mastrangeli (ECTM) have been awarded grants of 20KEUR by the Delft Bioengineering Institute (BEI) to pursue their research projects on ultrasound-based regeneration of neuronal circuits and medical implants to investigate cell mechanobiology, respectively.
Their multidisciplinary project proposals, conceived to bridge expertise among different departments within TU Delft, are among the 5 selected for the grants out of the 13 total submissions received by the BEI in response to their first call for proposals.
The projects will be run respectively in collaboration with Dr. Dimphna Meijer (TNW/BN) and Dr. Mohammad J. Mirzaali (3mE/BM).
Below are short summaries of the projects.

Regenerating neuronal circuits using ultrasound

People suffering from neurodegenerative disorders such as Alzheimer’s, Parkinson’s Disease and Multiple Sclerosis, have impaired neuronal circuits. Generation of new neuronal circuits by using a patient’s own stem cells may prove helpful in treating the disease. One of the difficulties in inducing neurons from stem cells, is the low efficiency rate we are able to achieve so far. In this project, BEI PIs Tiago Costa of Microelectronics (EWI) and Dimphna Meijer of Bionanoscience (TNW) join forces to explore the use of ultrasound for effectively building active neuronal networks from stem cells.

Project title: SoundCircuit: Regeneration of neuronal circuits using ultrasound
BEI PIs: Tiago Costa (EWI/ME), Dimphna Meijer (TNW/BN)

Medical implants to investigate cell mechanobiology

In order to study the cell’s behavior and differentiation, we need to be able to measure the mechanical, electrical, and biochemical signals that are dynamically transmitted throughout the cells. This requires the creation of biomaterial models equipped with different sensor types. In this project, BEI PIs Mohammad J. Mirzaali of Biomechanical Engineering (3mE) and Massimo Mastrangeli of Microelectronics (EWI) will team up to design, fabricate and test the proof-of-concept for medical implants equipped with force sensors that can reach a sensitivity level of one micronewton, so the mechanobiology of cells can be effectively investigated.

Project title: Sixth Sense Biomaterials
BEI PIs: Mohammad J. Mirzaali (3mE/BM), Massimo Mastrangeli (EWI/ME)

New sensor chips; low-cost, smart and efficient

In a greenhouse, cucumbers are growing beautifully. A grower is cultivating them under the most favourable conditions, closely monitoring the precise amount of water they need and whether the temperature is optimal, to ensure that the cucumbers that end up on your plate are juicy, flavoursome and green. The grower’s job is by no means carefree, however. What if the crop is blighted by some disease? One of the strategies that researchers are working on to prevent this involves an “electronic nose”. All plants, cucumbers included, emit a scent. An electronic nose can immediately detect whether something is wrong. The same technique can be applied in a chicken coop or cowshed. As soon as a disease breaks out, the electronic nose will detect it and give a warning.

Moore4Medical kicks off

The ECSEL Joint Undertaking Moore4Medical kicked off last June, 2020 with the overarching objective to accelerate innovation in electronic medical devices. Moore4Medical is masterminded by prof. Ronald Dekker (Philips Research & ECTM) and sees important involvement and vast opportunities for TU Delft’s Microelectronics department.

The project addresses emerging medical applications and technologies that offer significant new opportunities for the Electronic Systems & Components (ECS) industry, including: bioelectronic medicines, organ-on-chip, drug adherence monitoring, smart ultrasound, radiation free interventions and continuous monitoring. The new technologies will help fighting the increasing cost of healthcare by reducing the need for hospitalisation, helping to develop personalized therapies, and realising intelligent point-of-care diagnostic tools.

Moore4Medical will bring together 66 selected companies, universities and institutes from 12 countries who will develop open technology platforms for these emerging fields to help them bridge “the Valley of Death” in shorter time and at lower cost. Open technology platforms used by multiple users for multiple applications with the prospect of medium-to-high volume markets are an attractive proposition for the European ECS industry. The combination of typical MedTech and Pharma applications with an ECS style platform approach will enhance the competitiveness for the emerging medical domains addressed in Moore4Medical. With value and IP moving from the technology level towards applications and solutions, defragmentation and open technology platforms will be key in acquiring and maintaining a premier position for Europe in the forefront of affordable healthcare.

TU Delft’s Microelectronics department leads two of the six workpackages represented in Moore4Medical: the Implanatable Devices workpackage, led by Dr. Vasiliki “Vasso” Giagka (BE & Fraunhofer IZM), and the Organ-on-Chip workpackage, led by Dr. Massimo “Max” Mastrangeli (ECTM). Both workpackages will see the interaction and contribution of many world-class industrial and academic players to develop respectively bioelectronic medicines and smart multi-well plate platforms, and will provide a rich opportunity to capitalize on and further expand the standing expertise of the BE and ECTM groups of the department.

We wish Moore4Medical success!

Integrated devices for neuronal ultrasound stimulation

Neuronal interfaces have been widely developed in last decades with the purpose of providing a path for communication with the nervous system. The most common neuronal interfaces are based on electrical recording and stimulation of neuronal activity, which typically require surgical implantation of electrodes to achieve the necessary spatial resolution. To overcome the many hurdles and risks of surgery, non-invasive techniques to interface with the nervous system are currently being developed, and one of the most promising techniques uses focused ultrasound as a neuromodulation therapeutic modality. Due to its non-invasiveness, to achieve the necessary high spatial resolution, comparable to implantable electrodes, ultrasound transducers and electronics must be integrated in the same device. Its success may lead the way to surgery-free neuro-prosthetics and electroceuticals.

Vasiliki Giagka appointed associate editor for Bioelectronic Medicine

Bioelectronic Medicine (BM) is an open access, peer reviewed and relatively young journal published by the Feinstein Institute for Medical Research (in New York, NJ, USA) on BMC’s platform (part of Springer Nature): The journal brings together material science, molecular medicine, bioengineering, neuroscience, computer science and other related disciplines focused on new insights into the role of the nervous system in disease and health, and the importance of discovering new molecular mechanisms and technologies to treat disease. The journal has an expanded community and multidisciplinary audience from healthcare, technology and scientific research. Specialists writing for BM come from fields such as neuroscience, biology, bioengineering, electronics, computing, data analytics, molecular medicine, pharmaceuticals, medical devices, and personalized medicine and last named is extremely important in the upcoming domain of bioelectronic medicine, also known as electroceuticals, the electronic counterparts of pharmaceuticals.

At the core of electroceuticals is the electrical signal used by the nervous system to communicate information. Virtually every cell in the body is directly or indirectly controlled by these neural signals. Bioelectronic medicine technologies can record, stimulate and block neural signaling. Through its ability to manipulate neural signals it will change the way physicians treat diseases and conditions such as rheumatoid arthritis, Crohn's disease, diabetes, paralysis, bleeding and even cancer.

All articles published by BM are made freely and permanently accessible online immediately upon publication, without subscription charges or registration barriers. This nicely aligns with Delft University of Technology’s Open Acces policy.

For the same journal, Wouter Serdijn (also Section Bioelectronics at Delft University of Technology) has agreed to be serving as contributing editor. In this role, he will advise the editors of new trends, which may soon become prevalent in the field; keep up-to-date with the journal’s publications and provide feedback to the editors; contribute topic ideas and manuscripts to thematic series that will be implemented by the journal in the future; recommend articles from the field for publication.

Wouter Serdijn nieuw lid Wetenschappelijke Raad Medical Delta

Als lid heeft Wouter Serdijn de taak om bij te dragen aan het creëren van het wetenschappelijk programma en daarmee aan de visie van Medical Delta. Hij helpt mede vorm te geven aan onderzoeksprogramma’s en zal als ambassadeur optreden. Serdijn: “Met diverse langlopende samenwerkingen met zowel het ErasmusMC en het LUMC waren EWI en mijn sectie Bioelectronics al ‘Medical Delta’ vanaf het eerste uur. Niet zo verwonderlijk, want het behouden en terugwinnen van 100% gezondheid gerelateerde kwaliteit van leven vraagt steeds vaker micro-elektronische ondersteuning. Deze ondersteuning is belangrijk, zowel voor het begrijpen van de menselijke fysiologie en het menselijk gedrag als voor het betrouwbaar stellen van een diagnose, voor het nauwkeurig en ongestoord monitoren en voor een succesvolle persoonlijke behandeling. Ik denk dat dit goed aansluit bij de missie van Medical Delta en ik draag namens EWI graag een steentje bij.”

First Microelectronics Synergy Grants

According to Professor Geert Leus who heads the ME Research Committee, the Synergy Grants are also intended to kick-start the research of young faculty, as it can be quite challenging for them to obtain funding at the beginning of their research careers. The grants cover half the costs of a PhD candidate, with the rest coming from existing research funding. ‘The submitted proposals were carefully evaluated by the ME Research Committee on the basis of their scientific quality, their clarity and feasibility, the synergy between the participating sections, and the relationship to the departmental themes. The ME Management Team (MT) then decided to award Synergy Grants to the top three proposals.’


The aim of the grants is to encourage newly emerging combinations of technologies and to facilitate cross-overs between them, thus strengthening and broadening the department's research portfolio. This goal fits seamlessly within the research strategy of ME, which has defined itself around the four themes of Health & Wellbeing, XG, Safety & Security and Autonomous Systems to better address societal challenges.


Last week, the winners were received by the ME MT. They received flowers from the head of the department (Kofi Makinwa) and had the opportunity to briefly present their proposals to the assembled MT. Below are short descriptions of the successful proposals.

Akira Endo & Sten Vollebregt: ‘The aim of our project TANDEM: Terahertz Astronomy with Novel DiElectric Materials is to develop advanced dielectric materials to realize superconducting microstrip lines with very low losses in the frequency ranges of 2-10 GHz and 100-1000 GHz. The PhD candidate will combine the dielectric deposition, characterization, material expertise and facilities of the ECTM group and the Else Kooi Laboratory, and the submillimetre wave device measurement capability of the THz Sensing Group and SRON. The aim is not only to realize low loss dielectrics, but also to understand the underlying physics that governs these losses. If successful, these microstrips will be immediately applied to enhance the sensitivity of the DESHIMA spectrometer on the ASTE telescope in Chile.’

Bori Hunyadi: ‘On one hand, the vast complexity of the human brain (10^11 neurons and 10^14 connections) enables us to process large amounts of information in the fraction of a second. At the same time, imperfections of the wiring in this vast network cause devastating neurological and psychiatric conditions such as epilepsy or schizophrenia. Therefore, understanding brain function is one of the greatest and most important scientific challenges of our times. Brain function manifests as various physical phenomena (electrical or e.g. metabolic) at different spatial and temporal scales. Therefore, the PhD candidate working on this grant will develop a novel multimodal and multiresolution brain imaging paradigm combining EEG and a novel imaging technique, fUS. The specific engineering challenge is to understand and describe the fUS signal characteristics, deal with the large amount of data it records using efficient computational tools; and finally, formulate the specification of a dedicated non-invasive, multimodal, wearable EEG-fUS device.’

Virgilio Valente & Massimo Mastrangeli: ‘The seed money of the Synergy Grant will partially support a joint PhD candidate to investigate the tight integration of an heart-on-chip device with dedicated electronic instrumentation in the same platform. Our aim is to bring sensing and readout electronics as close as possible to a cardiac tissue cultivated within a dedicated micro physiological device. The grant helps promoting the logical convergence between current departmental research activities at ECTM and BE and within the Netherlands Organ-on-Chip Initiative (NOCI) on the development of instrumented organ-on-chip devices.’

Microelectronics at work for sustainable healthcare

The Medical Delta has launched twelve research programmes that work on technological solutions for sustainable care. EEMCS is represented in three programmes; Neurodelta (Wouter Serdijn), Medical Delta Cardiac Arrhythmia Lab (Wouter Serdijn and Alle-Jan van der Veen) and Ultrafast Ultrasound for the Heart and Brain (Michiel Pertijs), all part of the Microelectronics department.

In order to give the research programmes an extra impulse, a strategically important project is financed within each research programme.

Health Prototype Grant for Virgilio Valente

The TU Delft Health Initiative objective is to promote research in the field of healthcare at Delft University of Technology and they granted 13 out of total 26 applications. ‘Organs-on-chip (OoC) systems represent the new frontier in biomedical engineering, aiming at re-producing and mimicking key aspects of living organs on microengineered biosystems, by modeling the structural and functional complexity of organs, tissue to tissue interactions and cellular metabolism. Coupled to microfluidics and multi-parameter sensing, OoCs promise a significant revolution in the development of future targeted drugs and therapies, by providing a vital alternative to conven-tional cell cultures and animal models. By leveraging the distinctive features of modern complemen-tary metal-oxide semiconductor (CMOS) technology, coupled with high-density microelectrode array (MEA) systems, we can develop complex yet com-pact microelectronic biodevices capable of interact-ing with biological networks at a single-cell scale with unprecedented resolution and sensitivity. Im-pedance-based measurements (IM) have shown significant potential in monitoring cell and tissue contractions, morphology and cell-to-cell heteroge-neity. Impedance assays are currently routinely developed to assess drug toxicity in cardiac cell cul-tures. Commercial systems, including the xCELLI-gence RCTA by ACEA Biosystems, are based on the use of two electrodes for IM, which greatly limits the measurement resolution. To date, there is no com-mercial or research system capable of measuring impedance profiles from cardiac cell culture with high resolution.’

Read more about the work of Virgillio Valente:


The new frontier in smart and efficient diagnostics and analytics is represented by the fusion of semiconductor technologies and electrochemical sensors. BioCMOS devices, also known as Lab-on-CMOS or CMOS biosensors, consist of microelectronic interfaces with integrated high-density sensing elements. On top of these elements, biological and chemical assays can be directly performed, limiting considerably the need for additional external units. The Bioelectronics group is currently developing BioCMOS microsystems that target applications, including lab-on-chip and organ-on-chip platforms, point-of-care devices, implantable and injectable smart biosensors. By leveraging the distinctive features of modern complementary metal-oxide semiconductor (CMOS) technology, we can develop complex yet compact microelectronic bio-devices capable of interacting with biological networks at a cellular and molecular scale with unprecedented resolution and sensitivity. BioCMOS technology promises to play a key role in defining future targeted therapies and personalized medicine, cost-effective drug discovery and development, and efficient disease management strategies.

Samprajani Rout's ISCAS 2017 paper among top papers of the conference

ISCAS 2017 paper No. 1849, entitled “Structured Electronic Design of High-Pass ΣΔ Converters and Their Application to Cardiac Signal Acquisition” has been selected as one of the top contributions to the conference and an extended version of the paper has been invited for the TBioCAS Special Issue on ISCAS 2017. Authors of the paper are Samprajani Rout and Wouter Serdijn (Section Bioelectronics)

Abstract of the paper:

Achieving an accurate sub-Hz high-pass (HP) cutoff frequency and simultaneously a high accuracy of the transfer function is a challenge in the implementation of analog-to-digital converters for biomedical ExG signals. A structured electronic design approach based on state-space forms is proposed to develop HP modulators targeting high accuracy of the HP cutoff frequency and good linearity. Intermediate transfer functions are mathematically evaluated to compare the proposed HP Sigma-Delta topologies with respect to dynamic range. Finally, to illustrate the design method, an orthonormal HP Sigma-Delta modulator is designed to be implemented in 0.18 um technology which achieves a linearity of 12 bits.

NWO Demonstrator Grant awarded to Wouter Serdijn (Bioelectronics) and Cees-Jeroen Bes (in-Holland)

We recently developed a radically new technique, coined "additive companding", which solves important technological limitations of current neural recording systems. The technology has been patented, tested in the lab as proof of concept and is now ready to be developed further into a prototype. The foreseen prototype will allow for continuous and complete monitoring of neural activity, offers better performance and consumes drastically less volume (<400 µm x 400 µm x 400 µm) and energy (<<1 mW) than neural monitoring systems that currently exist or are under development. Clinically, the continuous and complete neural monitoring will offer new insights into the exact workings of nerve and brain tissue and it becomes possible to take the first step into the development of active medical implants that adjust themselves to the therapeutical needs of the patient without subjective measures. This, ultimately, enhances the health-related quality of life of patients with nerve and/or brain disorders and allows for a better treatment of a larger variety of nerve and brain disorders.

Alberto Gancedo-Reguilon awarded grant from the Delft University Fund and Electrical Engineering Alumni

A year ago our faculty took part in a pilot mailing of the University Fund to acquire funding by alumni. The result was positive with a result of €5000 to fund a student project at EEMCS.

The selected project for this funding is of a Spanish Bachelor student called Alberto Gancedo, who did an internship at our Micro-Electronics department (Section Bioelectronics) and at HealthTech BV. He is working on an aEEG Measurement System. His goal is to create a portable and affordable tool to track brain development of neonatal babies. These tools are already available, in developed countries. However, these are big and expensive devices. Alberto's tool can be used in any hospital, instead of just a few, and also in developing countries because of low production costs and its small size. The prototype is ready and Alberto will return to Delft in September to start his Masters' degree and to continue with this project.

About the University Fund

The University Fund would like to give young talent the chance to shine. Therefore they hand out funding for e.g. internships abroad, study trips and participation at international conferences. Excellent achievements are rewarded too with funding and recognition.

Boek: Vonken in de meterkast (Eng: Sparks in the meter box)

De schokkende strijd tegen depressie, Parkinson en andere hersenziekten

Ons brein is een meterkast, een netwerk van kabels dat het lichaam van stroom voorziet. Soms ontstaat er kortsluiting - kabels slijten, stoppen slaan door - met hersenziekten als gevolg. Op dat moment kan elektriciteit uitkomst bieden. Depressie, Parkinson en chronische pijn; met een stroomstoot kunnen steeds meer mensen van hun klachten worden afgeholpen.

In Vonken in de meterkast laat Bart Lutters ons kennismaken met de fascinerende wereld van de neurostimulatie; van de allereerste vonk tot de nieuwste wetenschappelijke ontwikkelingen. Wie is er ooit op het idee gekomen om een patiënt onder stroom te zetten? Welke ziektes kunnen er met stroom behandeld worden? En wat doet zo'n stroomstoot eigenlijk met onze hersenen? Vonken in de meterkast gaat over elektrische vissen en op-afstand bestuurbare stieren, robotarmen en gereanimeerde ledematen, maar vooral over hoe stroom ons al duizenden jaren beter maakt.

bart_luttersBart Lutters is zijn artsenopleiding aan het afronden (Selective Utrecht Medical Master) en wordt gefascineerd door alles wat met de hersenen te maken heeft. Hij heeft diverse prijzen gewonnen voor zijn onderzoek naar epilepsie en schrijft regelmatig over de geschiedenis van de geneeskunde in onder andere Brain, het toonaangevende wetenschappelijke tijdschrift op het gebied van de neurowetenschappen.

Vonken in de meterkast is vanaf 14 oktober verkrijgbaar in de betere boekhandel, ook online te bestellen via

New Book: Analog IC Design Techniques for Nanopower Biomedical Signal Processing


As the requirements for low power consumption and very small physical dimensions in portable, wearable and implantable medical devices are calling for integrated circuit design techniques using MOSFETs operating in the subthreshold regime, this book first revisits some well-known circuit techniques that use CMOS devices biased in subthreshold in order to establish nanopower integrated circuit designs. Based on the these findings, this book shows the development of a class-AB current-mode sample-and-hold circuit with an order of magnitude improvement in its figure of merit compared to other state-of-the-art designs. Also, the concepts and design procedures of 1) single-branch filters 2) follower-integrator-based lowpass filters and 3) modular transconductance reduction techniques for very low frequency filters are presented. Finally, to serve the requirement of a very large signal swing in an energy-based action potential detector, a nanopower class-AB current-mode analog multiplier is designed to handle input current amplitudes of more than 10 times the bias current of the multiplier circuit. The invented filter circuits have been fabricated in a standard 0.18 µ CMOS process in order to verify our circuit concepts and design procedures. Their experimental results are reported.

New book: Design of Efficient and Safe Neural Stimulators - A Multidisciplinary Approach

About this book:

This book discusses the design of neural stimulator systems which are used for the treatment of a wide variety of brain disorders such as Parkinson?s, depression and tinnitus. Whereas many existing books treating neural stimulation focus on one particular design aspect, such as the electrical design of the stimulator, this book uses a multidisciplinary approach: by combining the fields of neuroscience, electrophysiology and electrical engineering a thorough understanding of the complete neural stimulation chain is created (from the stimulation IC down to the neural cell). This multidisciplinary approach enables readers to gain new insights into stimulator design, while context is provided by presenting innovative design examples.

About the authors:

New project "Earlier recognition of cardiovascular diseases" approved

Atrial fibrillation (AF) is a progressive disease and associated with severe complications such as stroke. Early treatment of AF is of paramount importance as it inhibits disease progression from the treatable (recurrent intermittent) to the untreatable (permanent) stage of AF. However, early treatment is seriously hampered by lack of accurate diagnostic instruments to recognize patients who will develop new onset AF or progress to a severer form of the disease.

The goal of this project is to develop age and gender based, bio-electrical diagnostic tests, the invasive and non-invasive AF Fingerprint, which consists of electrical atrial signal profiles and levels of atrial specific tissue/blood biomarkers. In daily clinical practice, this novel diagnostic instrument can be used for early recognition or progression of AF by determination of stage of the electropathology. As such, AF Fingerprinting enables optimal AF treatment, thereby improving patient?s outcome.

The project is a collaboration between Erasmus University (Dept. Cardiology), VU Medical Center (Dept. Physiology), and TU Delft (Sections CAS and Bioelectronics), and will fund 4 PhD students.

Optogenetics: lighting the way to the future

The brain is the mystery of the human body. Neurons, as primary units of the nervous system, are joined together into a complicated biological interconnected network. A conventional method to manipulate the neural performance within this network is to use drugs that alter the chemical balance of the brain. However, a crucial aspect of the nervous systems is the electrical signalling between the neurons. Bioelectronics has advanced the neural modulation techniques beyond the conventional methods by developing electrical brain stimulation tools. Electrical brain stimulation is truly beneficial to understand the mechanism underlying neural behaviour, and develop novel therapeutic methods. Optogenetics is another breakthrough method in neural stimulation techniques, which has opened up entirely new avenues of research opportunities in the fields of neuroscience and bioelectronics. In this article, the basic principles of optogenetics and a state-of-the-art bioelectronics application for the treatment of epilepsy are described.

ISCAS 2015 Keynote Presentation Ronald Dekker online

Ronald Dekker's Keynote: ?From Chips for the Living to Living Chips?

Micro-fabricated devices are finding their way to the frontend of medical equipment, where they are the interface between body, or in general living tissue, and machine. They enable better and cheaper diagnostic equipment, they add ?eyes and ears? to minimally invasive instruments such as laparoscopic instruments and catheters, they allow for un-obtrusive monitoring of body functions, they add functionality to implants, and they enable the development of better and personalized medicines. Despite their great promise it has been proven difficult to bring these devices out of the laboratory phase into production. One of the reasons is the lack of a suitable fabrication infrastructure. Much more than standard CMOS or MEMS devices, these medical devices rely on the processing of novel materials, especially polymers, in combination with advanced molding, micro-fluidics, and assembly technologies. At the same time these devices have to be fabricated under strict quality control conditions in a certified production environment.

In the recently granted ECSEL project ?InForMed? a supply chain for the pilot fabrication of these medical devices is organized, which brings together key European technology partners in an integrated infrastructure linking research to pilot and high volume production. The pilot line is hosted by Philips Innovation Services, and open to third party users.

Speaker Biography:

Ronald Dekker received his MSc in Electrical Engineering from the Technical University of Eindhoven and his PhD from the Technical University of Delft. He joined Philips Research in 1988 where he worked on the development of RF technologies for mobile communication. Since 2000 his focus shifted to the integration of complex electronic sensor functionality on the tip of the smallest minimal invasive instruments such as catheters and guide-wires. In 2007 he was appointed part time professor at the Technical University of Delft with a focus on Organ-on-Chip devices. He published in leading Journals and conferences and holds in excess of 50 patents.

Leo de Vreede most entrepreneurial TU Delft scientist

During the annual YES!Delft Network Event on 18 May, the Delft Entrepreneurial Scientist Awards (DESA) were presented for researchers who encourage entrepreneurship. Dr Leo de Vreede of the Department of Microelectronics (EEMCS) was named the most entrepreneurial scientist at TU Delft.

Leo de Vreede is an associate professor at the Electronics Research Laboratory. In 2010, he founded the company Anteverta-mw. Building on the knowledge from his PhD research, the company developed a device that drastically accelerates and improves continuity testing of base stations for mobile telephony. As a result, data transfer is improved and energy consumption reduced. The TU Delft spin-off was taken over earlier this year by the American company Maury Microwave Corporation.

Jury chairman and President of the Executive Board Dirk Jan van den Berg praised De Vreede for his involvement with many spin-off companies and patent requests. The scientists received �valorisation bonuses� of �15,000 and �5,000 respectively.

Presentation on electroceuticals: getting better with electricity

On May 6, 2015, Collegerama of TU Delft made video recordings of the lecture Wouter Serdijn gave on Electroceuticals.

Electroceuticals are the electronic counterparts of pharmaceuticals and are miniature electronic devices that interact with the body in an electrical fashion.

In this talk Wouter Serdijn discusses: - neurostimulation and the need to make neurostimulators smaller, more power efficient and more intelligent; - optogenetic neuromodulation and the need to make this new neuromodulation modality operate in a closed-loop fashion; - neurosensing devices to make neurostimulators intelligent and thereby adjust themselves to the therapeutical needs of the patient; - autonomous wireless sensor nodes that can measure temperature or the electrocardiogram without the need for a battery; - an outlook into the future of electroceuticals with the promise to treat a larger variety of neurological and brain disorders better.

Delftse promovendus ontwikkelt volgende generatie neurostimulator

Marijn van Dongen is vandaag aan de TU Delft gepromoveerd op het chipontwerp voor een neurostimulator die klein genoeg is om in de schedel aan te brengen, dicht bij de plek waar gestimuleerd moet worden. Normaal gesproken worden neurostimulatoren uitgevoerd in de vormfactor van een pacemaker; vanwege hun afmetingen worden ze in de borst ge?mplanteerd en via onderhuidse draden verbonden met de elektroden in het hersenweefsel. Deze leads zijn echter gevoelig voor slijtage.

De batterij is echter een beperkende factor bij het miniaturiseren van deze apparaten. Daarom zocht de promovendus naar alternatieve stimulatiescenario?s die minder energie gebruiken. Uit simulaties en in vitro-proeven bleek het gebruik van hoogfrequente series stroompulsjes een veelbelovende aanpak. Dit soort pulsjes kunnen op een energie-effici?nte manier worden opgewekt dankzij het principe van een geschakelde voeding; een prototype van de neurostimulator was een factor drie zuiniger dan de huidige stimulatoren. Bovendien kan de pulsgebaseerde aanpak verschillende doelen tegelijkertijd activeren en daarmee de doelmatigheid van de behandeling verhogen.

De onderzoekers denken dat kleinere stimulatoren uiteindelijk breder ingezet kunnen worden. Op het moment wordt neurostimulatie vaak nog gezien als laatste redmiddel bij chronische aandoeningen als Parkinson, depressie, pijn en tinnitus. Er is echter nog een scala aan andere mogelijke toepassingen, zoals zoals epilepsie, verslavingen, migraine en dementie.

Congratulations to Prof. dr. Sarro with her royal honour

Professor Lina Sarro, professor of micro-electronics at the Faculty of Electrical Engineering, Mathematics and Computer Science, has been made a Knight in the Order of the Netherlands Lion, in The Hague.

She received the award because of her original research that resulted in a large scientific body of work and because of her in-depth involvement with her many students. Her pioneering work in the 1980s in the field of infrared sensors led to international acclaim. Since 1987, she has been in charge of research into micro and nanosystems (MEMS and NEMS) at the Else Kooi Lab, which was known previously as the Dimes Institute for Microsystems and Nanoelectronics.

Professor Sarro has published more than 200 articles in scientific journals and has received awards for her work on several occasions. In 2004, she received the Eurosensors Fellow Award, in 2007 the AISEM Career Award, and in 2012 the IEEE Sensors Council Meritorious Award. She is also a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and a fellow of the Institute of Electrical and Electronics Engineers. She has been praised on account of both her scientific work and her unfailing commitment to providing teaching of a high standard.

To her students, from both inside and outside the Netherlands, she is a figurehead. This applies perhaps in particular to female students and academics. In 2005, Professor Sarro became the first female to join the TU Delft Council of Professors. She is dedicated to emphasising the role of female scientists, in the conviction that it is a waste to use only half of our scientific assets. Her outstanding scientific reputation ensures that her voice is heard in this, and in other issues.

Efficacy of high frequency switched-mode stimulation in activating Purkinje cells; article published

We pre-published an important paper on a new neurostimulation paradigm on arXiv. The paper can be found here:

Abstract: This paper investigates the efficacy of high frequency switched-mode neural stimulation. Instead of using a constant stimulation amplitude, the stimulus is switched on and off repeatedly with a high frequency (up to 100kHz) duty cycled signal. By means of tissue modeling that includes the dynamic properties of both the tissue material as well as the axon membrane, it is first shown that switched-mode stimulation depolarizes the cell membrane in a similar way as classical constant amplitude stimulation. These findings are subsequently verified using in vitro experiments in which the response of a Purkinje cell is measured due to a stimulation signal in the molecular layer of the cerebellum of a mouse. For this purpose a stimulator circuit is developed that is able to produce a monophasic high frequency switched-mode stimulation signal. The results confirm the modeling by showing that switched-mode stimulation is able to induce similar responses in the Purkinje cell as classical stimulation using a constant current source. This conclusion opens up possibilities for novel stimulation designs that can improve the performance of the stimulator circuitry. Care has to be taken to avoid losses in the system due to the higher operating frequency.
