Abstract:

Self-healing conductive gels have been widely used in electronic skin, flexible robots and wearable devices due to their excellent mechanical properties, good biocompatibility and extended material life. The structural adjustability of gel matrix and the diversity of conductive material selection also provide the possibility for the preparation of flexible sensors with different functions. In this paper, the research progress of self-healing gel in the mechanical, photoelectric and biological aspects of flexible sensors is reviewed. The classification, forming mechanism and properties of self-healing gel were introduced. Finally, the paper discusses the existing problems in this field and gives a brief outlook on its future development.
