Abstract

Wearable devices are playing an important role in many fields, especially in the medical field, where they are responsible for the detection of vital signals, the quantification of health indicators, and the prevention of diseases. Nowadays, the demand for flexible wearable devices is increasing, and conductive hydrogels (CHs), as an important flexible material, have attracted a lot of attention from researchers because of their excellent properties such as flexibility and bio-adaptability. This paper introduces applications and recent advances of CHs in self-powered devices in the medical field, and divide into two aspects, according to their functions. CHs show excellent potential for applications, especially in human signal detection and biofluid analysis. The versatility of CHs makes them indispensable in the medical field, especially in precision medicine and personalised therapies. Finally, it also discusses the difficulties and challenges still faced by CHs in the integration of wearable devices, as well as the outlook for their future applications and development.
