The emerging applications of hydrogels in flexible electronics require hydrogels possess excellent anti-fatigue fracture and self-healing properties, while it remains an important unmet scientific challenge. Herein, inspired by human tissues, an effective and simple strategy is proposed to prepare a multifunctional hydrogel which is ultra-stretchable (>2900%), anti-fatigue-fracture, and self-healable. Moreover, the hydrogel exhibits high sensitivity in a wide strain window when used as strain sensors. More importantly, benefiting from the self-healing and anti-fatigue-fracture properties, the hydrogel can fully restore its sensing property after the cutting-and-healing process and keeps working for a very long time (>20000 cycles) even after severely damaged. This hydrogel shows great potential for future artificially intelligent and human-machine interface applications.
