Abstract
The study aims to investigate the functionality of a polyethylene glycol (PEG) and poly(3,4-ethylenedioxythiophene) (PEDOT) coated on nerve cuff electrode in in-vivo experiment. Drug-loaded biodegradable nanofiber was embedded in PEG hydrogel layer for suppression of early stage inflammatory response. However, PEG increased the impedance and, decreased the charge delivery capacity (CDC) of the nerve cuff electrode. PEDOT coating was introduced to minimize the negative effect of PEG. To evaluate the effect of conductive polymers, acute neuronal signals of PEDOT and PEG + PEDOT were acquired by in-vivo experiment. The results showed PEDOT was effective in recovering neuronal signals that were degraded by PEG layer.
