Biomimetic skin-like elec. materials have been rapidly developed for human-machine interfaces, health monitoring and soft robots. However, it is still a challenge of achieving a combination of the mech. and sensory properties like human skin. Here, a bioinspired phys. crosslinking hydrogel sensor is designed and fabricated based on an ionic conductive hydrogel with hybrid latex particles phys. crosslinked network. The hydrogels exhibit excellent mech. adaptability similar to human skin, including low modulus, excellent stretchability, robust elasticity, rapid self-recoverability and good antifatigue property. Moreover, the addition of LiCl gives hydrogel ideal ionic conducive behavior as high-performance wearable sensors. The hydrogel-based sensor exhibits high sensitivity (GF=5.44) at a broad strain window (0.25-2000%), excellent pressure sensing capability, rapid response time, negligible hysteresis and good durability. As a result, the hydrogel sensor can monitor various human motions, including large-scale joint bending, running and jumping, as well as tiny phonating and breathing. Therefore, the strategy will broaden the path for new generation of biomimetic sensors with skin-like mech. and strain and pressure sensing performances.
