Article: Role of wearable conjugated material pneumatic wrist in sports rehabilitation Journal: International Journal of Materials and Product Technology (IJMPT) 2026 Vol.70 No.5 pp.52 - 76 Abstract: In order to address the limitations of limited flexibility, poor mechanical durability, and insufficient biocompatibility of traditional wearable pneumatic wrists, this paper introduces a novel structural material of phosphorus conjugated microporous polymer as a pneumatic flexible actuator. Firstly, this paper prepares phosphorus containing conjugated microporous compounds using the Sonogashira method, and then uses the prepared phosphorus containing conjugated microporous compounds as materials for pneumatic flexible actuators to obtain actual actuators. On this basis, this paper combines commonly used materials to develop a wearable conjugate material pneumatic wrist. Finally, this paper conducts a control analysis on the deformation and mechanical properties of the pneumatic wrist. The research results indicate that when the wrist joint movement angle is 90 degrees, the output torque of the wearable conjugate material pneumatic wrist under a pressure of 0.02 MPa is 0.039. This indicates that the wearable conjugate material pneumatic wrist has good safety and adaptability. Inderscience Publishers - linking academia, business and industry through research
