Conductive, wearable, and flexible hydrogel-based sensors are considered as promising applications in human motion detection and physiological signal monitoring. However, it is still a problem to integrate multiple functions into one material for the next-generation smart devices. Herein, we fabricated an ionic/electronic dual conductive hydrogel by combining the chemically crosslinked polyacrylamide (PAM) and the physically crosslinked carboxymethyl chitosan-grafted-polyaniline (CMCS-g-PANI)/Ag+ network. The double-network hydrogel displays a high stretchability, repeatable adhesiveness, antibacterial activities, and biocompatibility. It also has high sensitivity and stable electrical performance for wearable strain sensors. Furthermore, we assembled a self-powered strain sensor based on the conversion of chemical energy to electrical energy. It can be used for human motion detection even without external power supply. This work provides an avenue for the development of multifunctional hydrogels with outstanding mechanical and electronic performances for application in wearable electronic devices.
