Dear Colleagues,

I am excited to advertise the talks of Jolien Pas and Gerwin Dijk from Department of Bioelectronics, Ecole Nationale Supérieure des Mines de Saint-Etienne, France. They will talk about the (probably near) future of electrophysiology, which still sounds a bit like science fiction – organic based electrodes and biodegradable guiding elements. The talks will take place in the lecture room of IEM HAS this Thursday (20 July) between 2 and 3 pm.

Title: A fast-dissolving bioresorbable shuttle for implanting flexible neural probes
Bioelectronics deals with the coupling of the electronics and biology. Organic materials are soft, biocompatible and conduct both ions and electrons which make them ideal for the interface with biology. Flexible neural probes have shown to be a promising alternative to conventional rigid probes for neural recording, however, lack stiffness for insertion into the brain. Our strategy is to coat the flexible probe with a bioresorbable polymer. This polymer provides the necessary stiffness to penetrate, is biodegradable and dissolves quickly after insertion. This is a big step forward and brings us closer to the ultimate aim of facilitating long-term recording with neural depth probes.

Title: Crystalline PEDOTSS Based Electrodes for Neural Recording
Organic based electronic devices have proven to be a promising candidate for monitoring of electrophysiological activity. The nowadays state of the art flexible ECoG probes are biocompatible, but chronic recording remains a challenge. One of the suspects is the degrading of the PEDOTSS material. Does crystalline PEDOTSS have the answer?

All are welcome!

best,
