Sleeping disorder is a major health threatening in high‐pace modern society. Characterizing sleep behavior with pressure‐sensitive, simple fabrication, and decent washability still remains a challenge and highly desired. Here, a pressure‐sensitive, large‐scale, and washable smart textile is reported based on triboelectric nanogenerator (TENG) array as bedsheet for real‐time and self‐powered sleep behavior monitoring. Fabricated by conductive fibers and elastomeric materials with a wave structure, the TENG units exhibit desirable features including high sensitivity, fast response time, durability, and water resistance, and are interconnected together, forming a pressure sensor array. Furthermore, highly integrated data acquisition, processing, and wireless transmission system is established and equipped with the sensor array to realize real‐time sleep behavior monitoring and sleep quality evaluation. Moreover, the smart textile can further serve as a self‐powered warning system in the case of an aged nonhospitalized patients falling down from the bed, which will immediately inform the medical staff. This work not only paves a new way for real‐time noninvasive sleep monitoring, but also presents a new perspective for the practical applications of remote clinical medical service.

基于摩擦纳米发电机阵列的大型可水洗智能纺织品，用于自供电睡眠监测

睡眠障碍是当今社会步伐高的主要健康威胁。通过压力敏感，简单的制造和良好的可洗性来表征睡眠行为仍然是一个挑战，并且是非常需要的。在此，报道了一种基于摩擦电纳米发电机（TENG）阵列的压敏，大型，可水洗的智能纺织品，作为床单，用于实时和自供电的睡眠行为监测。TENG单元由具有波动结构的导电纤维和弹性体材料制成，具有理想的功能，包括高灵敏度，快速响应时间，耐用性和耐水性，并且相互连接在一起，从而形成压力传感器阵列。此外，高度集成的数据采集，处理，建立无线传输系统，并配备传感器阵列，以实现实时睡眠行为监测和睡眠质量评估。此外，在老年非住院患者从床上跌落的情况下，智能纺织品还可以用作自动报警系统，这将立即通知医务人员。这项工作不仅为实时无创睡眠监测铺平了道路，而且为远程临床医疗服务的实际应用提供了新的视角。
