A large-scale untethered multiplexing triboelectric electronic skin is proposed with combined attributes including self-powered sensing, large stretchability and elasticity, robustness, and an ultra-low misrecognition rate of 0.20%. The proposed device are promising cornerstones of scalable untethered multiplexing self-powered e-skins, which are highly desired in practical applications, including haptics, human-device interfaces, medical care/assistance, and human-like/robotic perception.
