Continuous real-time human motion and heart-rate monitoring systems can provide vital clinical information for disease diagnosis, preventive healthcare and rehabilitation care. However, it is still a challenge to design wearable pressure/strain sensors with great flexibility and sustainable power for motion detection and physiological signal monitoring. Here, a self-powered laminated fabric sensor based on Schottky contact was successfully fabricated. This laminated fabric sensor was constructed by sandwiching the polypyrrole (PPy)-coated fabric with the Ni-coated fabric and Al plastic film. The electrical outputs under strain were attributed to the single Schottky contact between PPy and Al. This fabric sensor exhibited excellent stability under continuous quick cycling operation and at high relative humidity, which could be adapted to different human body parts for continuous motion detection and heart-rate monitoring. This work is of great significance to demonstrate a promising strategy toward self-powered wearable pressure sensors used for human motion detecting and hear-rate monitoring.

连续实时人体运动和心率监测系统可以为疾病诊断、预防保健和康复护理提供重要的临床信息。然而，设计具有极大灵活性和可持续能力的可穿戴压力/应变传感器用于运动检测和生理信号监测仍然是一个挑战。在这里，成功地制造了基于肖特基接触的自供电层压织物传感器。这种层压织物传感器是通过将聚吡咯 (PPy) 涂层织物与 Ni 涂层织物和 Al 塑料薄膜夹在中间而构成的。应变下的电输出归因于 PPy 和 Al 之间的单个肖特基接触。这种织物传感器在连续快速循环操作和高相对湿度下表现出优异的稳定性，可适应不同人体部位进行连续运动检测和心率监测。这项工作对于展示用于人体运动检测和心率监测的自供电可穿戴压力传感器的有前景的策略具有重要意义。
