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

连续被动运动 (CPM) 是关节损伤标准术后康复方案的辅助疗法。个性化术后康复和远程医疗的治疗策略非常需要实时监测膝关节实际弯曲角度的能力。在这里，我们报告了一种用于个性化康复和远程医疗的智能 CPM 系统，该系统基于具有令人印象深刻的机械性能（2.56 MPa 拉伸强度；11.63 MJ m ⁻³韧性），快速的自我恢复能力（60 s）和扩大环境耐受性（-60-45°C）。特别是ionotronic对循环应变传感响应速度快、稳定性好，保证了对实际关节弯曲角度的检测具有高灵敏度和可靠性。构建了由该离子电子和无线发射器组装而成的智能 CPM 系统，为开发数字智能医疗开辟了新天地，该医疗可以远程监控住院/在家患者的运动，这些患者使用 CPM 进行个性化的术后康复。
