Tough, rapid self-recovery and responsive organogel-based ionotronic for intelligent continuous passive motion system

Abstract Continuous passive motion (CPM) is an adjunct therapy to the standard postoperative rehabilitation regimen of joint injuries. The capability real-time monitoring actual bending angle knee joints highly desired for treatment strategies personalized and telemedicine. Here we report intelligent CPM system telemedicine based on flexible versatile ionotronic that possesses impressive mechanical properties (2.56 MPa tensile strength; 11.63 MJ m −3 toughness), fast self-recovery ability (60 s) broaden environmental tolerance (−60–45 °C). Especially, responds shows stability cyclic strain sensing, ensuring detection with high sensitivity reliability. assembled this a wireless transmitter was constructed, opening up horizon developing digital medical can remotely monitor movement hospitalized/at-home patients who use rehabilitation.
