▎ 摘　　要

NOVELTY - The system has a human body behavior capturing element, a resistance instrument, an electric signal conversion module, and an orthopaedic patient behavior analysis database. The human body action capturing element is provided with a composite conductive hydrogel with core-shell structure. The resistance meter records the change of hydrogel resistance in real time and transmits the resistance value to the electric signal converting module, which converts the resistance values into angle data of joint movement according to the standard curve of resistance and length obtained by pre-measuring and fitting and the standard curves of length and joint movement angle. The data is saved through the orthopedic patient behavior analysis database to judge the patient's recovery status and guide the formulation or correction of corresponding recovery plan. USE - Rehabilitation behavior monitoring and guidance system based on composite conductive hydrogel with a core-shell structure for postoperative joint injury patients. ADVANTAGE - The composite conductive hydrogel material has excellent high stretch, conductivity, force sensitivity, self-adhesion performance, cyclic stability, and excellent flexibility and tensile property, and is prepared by three-step in situ aggregate.
