The PVA/CNTs composite film presents a uniform three-dimensional mesh structure. The CNTs are uniformly dispersed in the hydrogel matrix to form a stable conductive network. The strain sensing performance of PVA/CNTs conductive hydrogel is investigated. It shows excellent dynamic response properties and stability with a GF of 6.34 within 0–10% tensile strain. The hysteresis of PVA/CNTs is as low as 0.333% ± 0.220%（mean ± SD）. Further application studies prove that the strain sensor based on PVA/CNTs conductive hydrogel can accurately monitor the motion status of human joints, and can effectively identify motion abnormalities in stroke patients in rehabilitation assistance assessment. conductive hydrogel strain sensor sensitivity hysteresis motion monitoring Full Text Additional Declarations No competing interests reported.
