A Better Way to Make Organic Bioelectronics
November 21, 2017 | Terry Sharrer
Most of today’s neural implants are made of metal. They have good conductivity between electrodes and neurons, but risk failure because of bio-incompatibility. This piece reports that engineers at the University of Houston and Penn State University have relied on an electronically conducting polymer for better functioning. Their process uses electrojetting and electrodeposition to form polymer “microcups” on the surface of the implant over a gold substrate. With better control over the size, shape and roughness of the microcups, the bioelectrodes had improved function. MORE
