MSc thesis project proposal
 Data Acquisition System for High-throughput Electrophysiological Signals Recording with Microelectrode Array ChipThe patch-clamp is the gold standard for in vitro measuring action potentials and ion channel currents of excitable cells like cardiomyocytes and neurons. However, it is very bulky and expensive, and the invasive operation on the cells only allows few hours of measurement time. Besides, it is not possible to study cell communications with very low throughput.
The CMOS-based microelectrode array (MEA) almost overcomes all the above limitations, and it is becoming more and more important for scientists to do high-throughput electrophysiological signal recording.
In this project, we have a vacancy for an MSc thesis project to develop the PCB test board and the software interface between our designed MEA chip and the computer. This system should have features to:
1) configure and control each pixel of the MEA;
2) choose different modalities to pace/record cells;
3) visualize the different signals, and
4) store the measured electrophysiological signals from cells in the computer.
