The emerging applications of hydrogels in flexible electronics require hydrogels to possess excellent anti-fatigue fracture and self-healing properties; this remains an important unmet scientific challenge. Herein, inspired by human tissues, an effective and simple strategy is proposed to prepare a multifunctional hydrogel that shows ultra-stretchable (>2900%), anti-fatigue-fracture, and self-healable properties. Moreover, the hydrogel exhibits high sensitivity in a wide strain window when used as a strain sensor. More importantly, benefiting from the self-healing and anti-fatigue-fracture properties, the sensing properties of the hydrogel are fully restored after a cutting-and-healing process and it keeps working for a very long time (>20 000 cycles) even after being severely damaged. This hydrogel shows great potential for future artificial intelligence and human–machine interface applications.

人体组织启发的抗疲劳断裂水凝胶，适用于敏感的宽范围人机界面†

水凝胶在柔性电子产品中的新兴应用要求水凝胶具有出色的抗疲劳断裂和自我修复性能；这仍然是一项重要的未满足的科学挑战。在本文中，受人体组织的启发，提出了一种有效而简单的策略来制备一种多功能水凝胶，该水凝胶具有超拉伸性（> 2900％），抗疲劳断裂和自愈特性。此外，当用作应变传感器时，水凝胶在宽的应变窗口中显示出高灵敏度。更重要的是，得益于自修复和抗疲劳断裂特性，水凝胶的感测特性在经过切割和修复过程后得以完全恢复，甚至可以长时间（> 2000次循环）工作。受到严重破坏后。
