Abstract

A nanomesh organic electrochemical transistor (NMOECT) is proposed. The NMOECT is a porous nanomesh structure, which enables the device to be comfortably laminated on human skin and simultaneously achieve local amplification. The acquisition and local amplification of the electrophysiological signals (electrocardiography) with DC-level cutoff were demonstrated using the NMOECT. A high signal-to-noise ratio of 25.896 dB was achieved. The proposed NMOECT could pave the way for on-skin electrodes that acquire high-quality biosignals.
