Bioelectronic skin sensors (BSSs) provide more opportunities for human health monitoring and therapy. However, most suffer from detachment caused by weak adhesion of polymers in humid physiological environments, which severely limits their applications. Here, we report a sweat-resistant BSS (SRBSS) with high sensitivity to bioelectric signals motion detection. This SRBSS not only exhibits strong dry, oily, sweaty but also has stable sensitive electrical signal responsiveness. The low swelling behavior anti-bacterial properties the hydrogel enables its use as an anti-sweating electronic interface devices long-term real-time signals. In addition, stretchability (800% elongation), instant self-healing (<1 s), moisture-proof, anti-freezing (−40°C) characteristics mean that composites could be applied wearable bioelectronic complex conditions human-computer interactions, providing new insight into design sensors.
