On the Stability of PEDOT as Coating Material for Active Neural Implants
نویسندگان
چکیده
This paper is about the stability of PEDOT coatings under high loads of current pulses. Test parameters were chosen to match many peripheral nervous system (PNS) applications in regard of charge injection, pulse width and repetition frequency. PEDOT coatings were characterized with electrochemical impedance spectroscopes (EIS) and pulse tests. No decrease in charge injection capacities could be detected after ten million pulses, suggesting a stable coating for at least this time frame with superior properties in regard of conventional platinum electrodes.

In Vivo Electrochemical Analysis of a PEDOT/MWCNT Neural Electrode Coating
Neural electrodes hold tremendous potential for improving understanding of brain function and restoring lost neurological functions. Multi-walled carbon nanotube (MWCNT) and dexamethasone (Dex)-doped poly(3,4-ethylenedioxythiophene) (PEDOT) coatings have shown promise to improve chronic neural electrode performance. Here, we employ electrochemical techniques to characterize the coating in vivo....
متن کاملFreeze Drying Improves the Shelf-Life of Conductive Polymer Modified Neural Electrodes
Coating microelectrodes with conductive polymer is widely recognized to decrease impedance and improve performance of implantable neural devices during recording and stimulation. A concern for wide-spread use of this approach is shelf-life, i.e., the electrochemical stability of the coated microelectrodes prior to use. In this work, we investigated the possibility of using the freeze-drying pro...
