The metal-organic frameworks (MOFs) ZIF-8 nanoparticles and PNIPAM-AAM hydrogel matrix were combined to prepare NA-ZIF-8 composite hydrogel with high stretchability and fatigue resistance by one-pot method.The mechanical properties of the hydrogel were significantly improved while maintaining the temperature response performance of the NIPAM hydrogel.In addition,the hydrogel used as strain sensor had the following advantages:wide working range,fast response time and high stability etc.And the NA-ZIF-8 hydrogel strain sensor can quickly and precisely monitor various tiny motions of the human body through electrical signal changes.
