可穿戴大面积织物能量采集器和传感器的发展因其在下一代自主可穿戴医疗技术中的应用前景而备受关注。在这里，我们展示了一种新型的“单线”摩擦电纳米发电机及其在弹性织物能量采集和传感中的应用。由一根硅橡胶涂覆的不锈钢丝组成的集能线，可以在与皮肤接触时提取能量。通过在弹性织物上将能量收集线缝制成蛇形，实现了一种高度可伸缩和可伸缩的滕氏纺织品，以清除各种人体运动能量。收集的能量能够可持续地为一款商业智能手表提供动力。此外，简化的单个摩擦电线可以应用于基于线程的自供电和主动传感的广泛用途，包括手势传感、人机交互界面和人体生理信号监测。在与微控制器集成后，将展示更复杂的系统，如无线可穿戴键盘和智能床。这些结果表明，新设计的单线Teng具有交互性、响应性、可缝合性和保形功能的优势，可以满足从可穿戴和可拉伸的能量收集器到智能布基物品等各种领域的应用需求。
The development of wearable and large-area fabric energy harvester and sensor has received great attention due to their promising applications in next-generation autonomous and wearable healthcare technologies. Here, a new type of "single" thread-based triboelectric nanogenerator (TENG) and its uses in elastically textile-based energy harvesting and sensing have been demonstrated. The energy-harvesting thread composed by one silicone-rubber-coated stainless-steel thread can extract energy during contact with skin. With sewing the energy-harvesting thread into a serpentine shape on an elastic textile, a highly stretchable and scalable TENG textile is realized to scavenge various kinds of human-motion energy. The collected energy is capable to sustainably power a commercial smart watch. Moreover, the simplified single triboelectric thread can be applied in a wide range of thread-based self-powered and active sensing uses, including gesture sensing, human-interactive interfaces, and human physiological signal monitoring. After integration with microcontrollers, more complicated systems, such as wireless wearable keyboards and smart beds, are demonstrated. These results show that the newly designed single-thread-based TENG, with the advantage of interactive, responsive, sewable, and conformal features, can meet application needs of a vast variety of fields, ranging from wearable and stretchable energy harvesters to smart cloth-based articles.
