Abstract

Abstract : Conductive Dry Electrode for Electrophysiological Signal Detection In article number 2200594, Young‐Joon Kim, Hocheon Yoo, and co‐workers demonstrate that a biodegradable polymeric composite electrode allows long‐term and sensitive electrophysiological biosignal sensing. The robust mechano‐electrical properties of the dry organic film are achieved through the weak‐molecular interaction between the PEDOT:PSS, HEC, and dopamine. Consequently, the epidermal electrodes successively detect the ECG and EMG signals using a wireless measurement system.
