Conformal Micropatterned Organic-Metal Electrodes for Physiological Recording

By: K. Queener n , P. Ahmmed n , M. Victorio*, J. Twiddy n, A. Dehn n, A. Brewer n, E. Lobaton n , A. Bozkurt n , V. Pozdin*, M. Daniele n 

Contributors: K. Queener n , P. Ahmmed n , M. Victorio*, J. Twiddy n, A. Dehn n, A. Brewer n, E. Lobaton n , . al.

author keywords: conformal electrodes; biopotential recording; microfabrication; photolithography; PEDOT:PSS
topics (OpenAlex): Advanced Sensor and Energy Harvesting Materials; Muscle activation and electromyography studies; Neuroscience and Neural Engineering
TL;DR: CMOM electrodes were characterized then evaluated in vivo against commercial-off-the-shelf electrodes and PEDOT:PSS coating found to reduce the overall impedance in each electrode variant, resulting in a >97% decrease in impedance at low frequencies. (via Semantic Scholar)
