Current development of wearable sensors based on nanosheets and applications

In the past few years, a significant amount of breakthroughs in the research field of nanosheets have made them possible for broad applications of wearable sensors. Compared with nanoparticles (NPs) and one-dimensional nanofibers or nanotubes, however, nanosheets (as two-dimensional materials) manifest superior physical and electrochemical properties and the potential of constructing wearable electronic composites. The high surface-to-volume ratio and high flexibility of the nanosheets endow the sensors with small size and high stability under deformation, making sensors portable and wearable. In this review, the state-of-the-art advances of wearable sensors based on nanosheets are discussed systematically in three categories, e.g., motion detection, bio-signal monitoring, and environmental applications. Finally, the future perspectives and outlooks towards the development of wearable sensors are prospected. (C) 2021 Elsevier B.V. All rights reserved.
