Abstract

Abstract: The development of biocompatible electronic skin (e‐skin) is foremost to next generation bio‐electronics that enables diverse applications in wearable, medical, artificial intelligence, and human machine interface. As serving a multifunctional platform, numerous types of electronic components (eg, sensors, actuators, etc.) required in e‐skin, which requires users to power them in a regular manner. In this regard, researchers recently have reported compact, light, flexible, and stretchable energy harvesters are expected to revolutionize the market in wearable electronics, in particular for e‐skin. The self‐powered e‐skin can power by itself, without any external energy from other devices. In this review, the recent progress of triboelectric nanogenerators based on diverse materials such as hydrogel, healable, stretchable, biocompatible, and biodegradable for developing self‐powered e‐skin is discussed. Abstract : This review article presents a comprehensive overview of the development of biocompatible electronic skin (e‐skin), emphasis on thereof self‐powered mode driven by triboelectric nanogenerators (TENGs). Among numerous biocompatible and biodegradable materials, hydrogels have been reported to be interestingly self‐healable. We highlight the recent progress of hydrogels based TENGs for developing self‐healing, biocompatible, biodegradable, and highly stretchable e‐skins.
