主 题：durability conformal satisfy
摘 要：Reliable,wide range,and highly sensitive joint movement monitoring is essential for training activities,human behavior analysis,and human-machine ***,most current motion sensors work on the nano/microcracks induced by the tensile deformation on the convex surface of joints during joint movements,which cannot satisfy requirements of ultrawide detectable angle range,high angle sensitivity,conformability,and consistence under cyclic *** nature,scorpions sense small vibrations by allowing for compression strain conversion from external mechanical vibrations through crack-shaped slit ***,we demonstrated that ultraconformal sensors based on controlled slit structures,inspired by the geometry of a scorpion’s slit sensilla,exhibit high sensitivity(0.45%deg^(-1)),ultralow angle detection threshold(~15°),fast response/relaxation times(115/72 ms),wide range(15°~120°),and durability(over 1000 cycles).Also,a user-friendly,hybrid sign language system has been developed to realize Chinese and American sign language recognition and feedback through video and speech broadcasts,making these conformal motion sensors promising candidates for joint movement monitoring in wearable electronics and robotics technology.
