Long-term, real-time, and comfortable epidermal electronics are of great practical importance for healthcare monitoring human–machine interaction. However, traditional physiological signal confined by the specific clinical sites unreliability electrodes leads to restrictions on its application. Herein, we constructed a solution-processed submicron (down 230 nm), free-standing, breathable sandwich-structured hybrid electrode composed silver nanowire network with conductive polymer film, which is conformal, water-permeable, noninvasive skin while achieving good acquisition ability. The free-standing prepared via an in situ capillary force lift-off process can be transferred onto complex surfaces. whole complete solution that facilitates large-area preparation light-weight exhibit high optical transmittance, electrical conductivity, gas/ion permeability. When attached skin, imperceptible films show conformality low impedance, thus exhibiting significantly improved electrocardiology electromyogram performance compared commercial gel electrodes.
