We conduct research towards implantable integrated circuits and systems for neuro- and bio-interfaces. While former research contributed ground-breaking designs for sub- and epiretinal implants, our recent work focusses on neural recording interfaces, efficient functional electrical stimulation, and the combination of both which is neuromodulation. Low-power data communication, wireless powering and enhanced saftey are futher core topics of our work. Our circuits and systems are tailored together with collaboration partners for human implantation.

D. Fritschi: Cardiovascular disease is a major cause of death in Europe [1]. Self-expandable implants, so-called stents, have been used in medicine for several decades to reopen narrowed blood vessels and reduce mortality from cardiovascular disease. However, this artificial device can cause e.g. in-stent restenosis due to the body's self-healing mechanism, which narrows the blood vessel again ... [more]
