In recent years, wearable multifunctional sensors have experienced tremendous development due to their wide application prospects in areas such as Internet of Things, human-machine interactions, and personal health monitoring. These sensors require not only superior capability to distinguish multiple stimuli with effective signal decoupling, but also good wearable comfortability and even self-powered features. In this work, a highly stretchable, breathable, and self-powered sensor enabling simultaneous detection of large tensile strain and temperature stimuli has been designed and successfully fabricated. In this sensor, two functional layers for strain sensing and temperature sensing with high mechanical compatibility are independently arranged, thereby facilitating effective signal decoupling upon the strain-temperature coupled dual-stimuli. Notably, this strain-temperature dual-functional sensor exhibits not only a high stretchability with a wide working range of up to 100%, but also excellent strain sensing capability and temperature sensing capability. Based on a rational electric circuit design, the sensor further enables synchronous strain-temperature monitoring in a self-powered mode. Its practical applications for human motion monitoring, hyperthermia, and physiotherapy are demonstrated. Combining the excellent sensing performance and wearability, the sensor developed in this work can hold great promise for future wearable electronics and E-skin applications.

具有层压结构的高度可拉伸、透气和自供电应变温度双功能传感器,用于健康监测、热疗和物理治疗应用

近年来,可穿戴多功能传感器因其在物联网、人机交互、个人健康监测等领域的广泛应用前景而获得了巨大的发展。这些传感器不仅需要通过有效的信号解耦来区分多种刺激的卓越能力,还需要良好的可穿戴舒适性,甚至是自供电功能。在这项工作中,设计并成功制造了一种高度可拉伸、透气和自供电的传感器,能够同时检测大的拉伸应变和温度刺激。在该传感器中,具有高机械兼容性的应变传感和温度传感两个功能层独立布置,从而促进了对应变-温度耦合双刺激的有效信号解耦。值得注意的是,这种应变-温度双功能传感器不仅具有高达100%的宽工作范围的高拉伸性,而且还具有出色的应变传感能力和温度传感能力。基于合理的电路设计,该传感器进一步实现了自供电模式下的同步应变-温度监测。展示了其在人体运动监测、热疗和物理治疗方面的实际应用。结合出色的传感性能和可穿戴性,这项工作中开发的传感器可以为未来的可穿戴电子产品和电子皮肤应用带来巨大的希望。基于合理的电路设计,该传感器进一步实现了自供电模式下的同步应变-温度监测。展示了其在人体运动监测、热疗和物理治疗方面的实际应用。结合出色的传感性能和可穿戴性,这项工作中开发的传感器可以为未来的可穿戴电子产品和电子皮肤应用带来巨大的希望。基于合理的电路设计,该传感器进一步实现了自供电模式下的同步应变-温度监测。展示了其在人体运动监测、热疗和物理治疗方面的实际应用。结合出色的传感性能和可穿戴性,这项工作中开发的传感器可以为未来的可穿戴电子产品和电子皮肤应用带来巨大的希望。
