Flexible and multifunctional electronic skin (e-skin) has received remarkable attention for its potential applications in health monitoring, human-machine interface, artificial sensory nerves. However, conventional e-skins require complex material systems, sophisticated fabrication, external power supplies, leading to increased preparation cost duration, thus hindering their large-scale utilization. Herein, a self-powered e-skin system with properties of pressure, temperature, underwater sensing, photothermal heating is designed based on carbon nanotubes/poly(dimethylsiloxane) (CNT/PDMS) acting as both the sensing layer cathode supply. Our micropyramidal structured exhibits outstanding pressure sensitivity (1.51 × 103 kPa-1) over wide range (2.5-255.7 kPa) maintains ultralong-term durability (>20 000 cycles). It can also provide personalized therapy at an adjustable temperature (40-110 °C) area under near-infrared irradiation due effect CNTs, being detected synchronously by current signals. Additionally, hydrophobicity CNT/PDMS film endows our device capability. Furthermore, practical healthcare have been demonstrated reliable signal quality stability, such daily activities movements/temperature SOS Morse code communication, interface. This work could insight developing simple, stable, wearable devices self-power supply multifunction.
