在物联网（IoT）时代，希望为分散式电子设备配备分布式电源。基于纤维的摩擦电纳米发电机（FTENG）提供了最好的解决方案之一，因为它具有高效率，易于部署，出色的耐磨性，低成本和生态友好性。与其他形式的TENG相比，它可以编织成织物作为可穿戴设备，提供良好的紧凑性和舒适性。然而，工业织机兼容的FTENG尚未制造;纤维直径和长度是大规模织造中的典型挑战。本文介绍了热拉伸工艺（TDP），以生产与工业织机兼容的FTENG。聚合物包层和金属芯光纤的直径已经减小到接近350 μ m，单根光纤的长度已经扩大到亚公里。手工编织和织布机编织的样本都被证明，显示出良好的灵活性，拉伸性，功率密度，稳定性，耐洗性和透气性。除了用作电源之外，这种样本还被用作用于身体运动监测和通信的自供电传感器。这些应用表明，热拉伸FTENG可以作为现代电子产品中功能强大且可靠的可穿戴设备。
In the era of the internet of things (IoTs), it is desired to equip the decentralized electronics with distributed power sources. The fiber-based triboelectric nanogenerator (FTENG) provides one of the soundest solutions due to its high efficiency, easy deployment, excellent wearability, low cost, and eco-friendliness. Compared with other forms of TENGs, it can be woven into fabrics as wearable devices, offering good compactness and comfortability. However, the industrial-loom-compatible FTENGs have yet to be fabricated; the fiber diameter and length are typical challenges in the large scale weaving. In this paper, the thermal drawing process (TDP) is introduced to produce FTENGs that are compatible with industrial looms. The diameter of the polymer-cladding and metal-core fiber has been reduced to similar to 350 mu m, and the length of a single fiber has been scaled up to sub-kilometer. Both hand-woven and loom-woven swatches are demonstrated, showing good flexibility, stretchability, power density, stability, washability, and breathability. Besides serving as power sources, such swatches have been used as self-powered sensors for body motion monitoring and communication. These applications show that the thermally drawn FTENGs can serve as powerful and reliable wearable devices in modern electronics.
