摘要
Flexible and dry electrodes have attracted huge attention due to their potential application in long-term electrophysiological signal monitoring. In this work, we present a novel method to pattern silver nanowires (AgNWs) on a polydimethylsiloxane (PDMS) substrate-based dry electrodes by a vacuum filtration method for electrophysiological signal monitoring. The Scotch tape peel-off test confirms the excellent adhesion of the patterned AgNWs on a PDMS substrate. The cytotoxicity of the proposed electrode is detected by an MTT assay method, and 90% cell viability is observed for the period of one week, indicating no cytotoxic effect on living cells. The signal to noise ratios of the conventional wet Ag/AgCl and dry AgNW/PDMS electrodes are 24.6 and 25.4 dB, indicating that AgNW/PDMS dry electrodes measure a high-quality electrophysiological signal when compared with that of the conventional Ag/AgCl wet electrodes.
