Flexible silver nanowire-polymer conductive films for electrophysiological detection

Abstract

Abstract This study employed polydimethylsiloxane and silver nanowire (AgNW) to prepare polymer films for electrocardiography and electromyography sensing. Two approaches were employed to prepare AgNW-based polymer films. In the first approach, AgNW was embedded in polydimethylsiloxane through polymer infiltration. In the second approach, AgNW was applied to the surface of the polymer. The fabricated polymer films were effectively employed in electrocardiography and electromyography measurements, revealing efficiency comparable to traditional silver/silver chloride wet electrodes. The presented approaches are inexpensive and suited to mass production and thus hold great promise in the fabrication of polymer electrodes for medical monitoring.
