ReaSONS 2 Demo: Realtime Sensing of Neural Signals Demonstrator (R2D)

Themes: Analog and Mixed-Mode Integrated Circuits and Systems, Biosignal acquisition, conditioning and processing, Neuroprosthetics, - stimulation and -modulation

Demonstrator of recording tiny neural signals on top of the stimulus and artifact. NWO Demonstrator Grant.
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.
