Abstract

Electronic skin based on nanomaterials has great potential for material detection and health monitoring. This paper first outlines the current development of physical sensors for electronic skin based on nanomaterials. Secondly, according to the different kinds of propagation signals, it reviews the research on physical sensors based on different nanomaterials sensing. Strain signals, temperature signals and electrophysiological signals are the main types of nanomaterials transduction. It discusses the different mechanisms, research processes and advantages of the different ways of constituting physical sensors after sensing signals. In particular, it reviews the comparison of nanomaterials constituting sensors with conventional approaches and innovations in the performance of advanced electronic skin sensors. According to the technologies used in them, it reviews the particularities of each study in detail. It analytically summarizes their application in electronic skin as a novel bionic monitoring element. Finally, it also summarizes and proposes future directions for the development of electronic skins composed of physical sensors based on nanomaterials.
