▎ 摘　　要

This article presents the fabrication of a flexible, conductive, and chemically reduced graphene oxide (CRGO)based dry electrodes for electrocardiograph signal measurement using touch sensing mechanism. We designed the dry electrode sensor to eliminate the noise and inconvenience associated to the use of electrolytic gel. CRGO electrodes were used as touch sensors for obtaining high quality biopotential signal and human fingers were utilized to maintain good contact to enable minimizing the skin -electrode contact impedance. The surface resistivity of the CRGO electrode was found 28 Omega/square. The proposed method is a simple and cost-effective fabrication process for a flexible conducting CRGO-coated nylon membrane for electrocardiograph (ECG) signal monitoring application.
