In recent years, with the rapid development of wearable devices, smart materials and flexible electronics, self-powered electronic skin has received widespread attention as a novel multifunctional sensor platform.. Self-powered electronic skin is mainly based on the piezoelectric effect (PE), thermoelectric effect (TE) and photoelectric effect (OE) and other physical mechanisms By converting mechanical, thermal and light energy in the environment into electrical energy, it can achieve self-sufficiency in energy supply. This paper will discuss the multifunctional characteristics of self-powered electronic skin, especially its application potential in health monitoring, environmental monitoring and smart wearable devices. Self-powered electronic skin is mainly based on the piezoelectric effect (PE), thermoelectric effect (TE) and photoelectric effect (OE) and other physical mechanisms, by converting mechanical, thermal and light energy in the environment into electrical energy, it can achieve self-sufficiency in energy supply. This technology not only shows important application value in the field of physiological signal monitoring and disease early warning, but also provides a new research direction for future personalized medicine, environmental protection and smart device design.
