While triboelectric nanogenerated knitted fabrics are regarded as a state-of-the-art and reliable energy source for wearable electronics, there are two bottlenecks in their widespread applications: few mass-manufacturing strategies and low power output. Here, by mature weft-knitted technologies, a 3D single-faced jacquard pile fabric TENG (SJPF-TENG) with the merits of high surface pile density, excellent comfort and breathability, good thermal insulation property, and superior durability, is mass-produced. Based on the high-density pile structure (about 16128 piles per cm), the surface area of pile fabrics is 42.2 times that of the plain structure, which endows the SJPF-TENG with higher electrical outputs and good detection precision. With a peak power density of 1.4 W m (dozens of times that of conventional textile-based TENGs), the SJPF-TENG is capable of lighting up 1392 light-emitting diodes, powering miniature electronics, and charging various capacitors. Furthermore, a self-powered remote control, an intelligent alphabet writing pad, a smart fluff carpet, and a proof-of-concept fluff keyboard array with 3×3 sensing pixels are demonstrated to verify its outstanding sensing performance. Our results provide a massive prospect for high-power textile-based TENGs in large-area energy harvesting, smart-home control systems, entertainment, elder healthcare, and security warnings.

用于智能家居和医疗保健的仿生毛皮针织摩擦电织物的量产

虽然摩擦起电纳米针织物被认为是可穿戴电子产品最先进且可靠的能源，但其广泛应用存在两个瓶颈：大规模制造策略少和功率输出低。在这里，利用成熟的纬编技术，量产了具有表面绒毛密度高、舒适透气性好、保温性能好、耐用性优越等优点的3D单面提花起绒面料TENG（SJPF-TENG） 。基于高密度绒头结构（约16128绒头/厘米），绒头织物的表面积是平纹结构的42.2倍，这使得SJPF-TENG具有更高的电输出和良好的检测精度。 SJPF-TENG的峰值功率密度为1.4 W m（是传统纺织TENG的数十倍），能够点亮1392个发光二极管，为微型电子设备供电，并为各种电容器充电。此外，还展示了自供电遥控器、智能字母书写板、智能绒毛地毯以及具有3×3传感像素的概念验证绒毛键盘阵列，以验证其出色的传感性能。我们的研究结果为基于织物的高功率 TENG 在大面积能量收集、智能家居控制系统、娱乐、老年保健和安全预警方面提供了广阔的前景。
