Ultra-stretchable, self-recoverable, notch-insensitive, self-healable and adhesive hydrogel enabled by synergetic hydrogen and dipole–dipole crosslinking

Abstract

), notable adhesive properties and superior self-healing capabilities. The incorporation of LiCl imparts conductivity to the hydrogel, making it suitable for wearable strain sensors that can accurately monitor human motion. These results demonstrate the successful development of an ultra-stretchable, self-recoverable, notch-insensitive, self-healable and adhesive hydrogel with significant potential for advanced applications in wearable electronics and healthcare monitoring devices. This work represents a significant step forward in the design of multifunctional hydrogels, offering new pathways for the development of next-generation soft materials with enhanced mechanical and functional properties.
