Abstract

Wearable electrophysiological monitoring based on hydrogel electrodes is pivotal for decoding the body's "electrical language", yet fundamentally hampered by the unstable mechano-electrical interface between flexible electrodes and the skin caused by dehydration and poor breathability. Here, we demonstrate a symbiotic interface between an embedded-interfacial enhanced breathable conductive hydroge…
