Abstract The development of ultrasensitive, anti-jamming, and durable sensors that can precisely distinguish different human body motions are great importance for smart health monitoring diagnosis. Physical implementation such flexible is still a challenge at the moment. Combining designs advanced material showing excellent electrochemical properties with facilitative structure engineering, high-performance satisfy both signal detecting recognition requirements may be made possible. Here we report first metal–organic framework-based strain sensor accurate detection noise-screening properties. Upon doping tricarboxytriphenyl amine-based framework nanofilm iodine, two-terminal device exhibits ultrahigh sensitivity gauge factor exceeding 10,000 in 2.5% to 3.3% deformation range over 5000 dynamic operating cycles out-of-scale capability. easily differentiate moderate muscle hyperspasmia from subtle swaying vigorous sporting activities.
