摘　　要：Polyvinyl alcohol(PVA)hydrogels doped with cyclohexane-1,2,3,4,5,6-hexacarboxylic acid(CHA)were successfully prepared during drying and swelling.Structural and morphological characterizations suggest the carboxyl and hydroxyl groups in the material undergo esterification during the preparation of the material,which contributes to the high transparency with 90%transmittance in the 400 to 800 nm range and robust mechanical properties of the material with a tensile strength at a break of 27.55 MPa.It is noteworthy that the bending and torsion angles exhibit a strong linear correlation with electrical resistance,enabling the monitoring of the bending motion state of each human body segment.
