Abstract

This paper summarizes recent advances in the design and realization of PDMS-based, high-performance conductive hydrogel-based, MXene-based, CNT-GNP-based and Ultra-thin gold nanowires-based sensors. Wearable strain sensors are widely used in medical detector, dynamic monitoring, and human-computer interaction due to their excellent stretchability, sensitivity, and durability. At this stage, technologies such as graphene and nanocellulose thin film mosaic, neuron-like structures, GNP-CNT hybrid films, and ultrathin gold nanowire fabrication have been successfully utilized in the development of higher performance and higher quality wearable strain sensors. Different strain sensors have different advantages in terms of different mechanical properties. The text compares the advantages of strain sensors made of different materials applied to different devices. Finally, it looks at the future prospects of wearable strain sensors. Although sensors have made great progress in the application of products in medicine, life and other aspects, it is still not possible to put these products into use on a large scale. Corresponding products still face problems and challenges to improve and enhance their performance.
