Here we report a fully flexible, foldable nanopatterned wearable triboelectric nanogenerator (WTNG) with high power-generating performance and mechanical robustness. Both a silver (Ag)-coated textile and polydimethylsiloxane (PDMS) nanopatterns based on ZnO nanorod arrays on a Ag-coated textile template were used as active triboelectric materials. A high output voltage and current of about 120 V and 65 μA, respectively, were observed from a nanopatterned PDMS-based WTNG, while an output voltage and current of 30 V and 20 μA were obtained by the non-nanopatterned flat PDMS-based WTNG under the same compressive force of 10 kgf. Furthermore, very high voltage and current outputs with an average value of 170 V and 120 μA, respectively, were obtained from a four-layer-stacked WTNG under the same compressive force. Notably it was found there are no significant differences in the output voltages measured from the multilayer-stacked WTNG over 12 000 cycles, confirming the excellent mechanical durability of WTNGs. Finally, we successfully demonstrated the self-powered operation of light-emitting diodes, a liquid crystal display, and a keyless vehicle entry system only with the output power of our WTNG without any help of external power sources.
在这里，我们报告了一种完全灵活、可折叠的纳米图案化可穿戴摩擦纳米发电机（WTNG），它具有高发电性能和机械鲁棒性。银（Ag）涂层纺织品和基于 ZnO 纳米棒阵列的聚二甲基硅氧烷（PDMS）纳米图案均用作有源摩擦电材料。从基于 PDMS 的纳米图案 WTNG 中观察到约 120 V 和 65 μA 的高输出电压和电流，而在相同的 10 kgf 压缩力下，非纳米图案化的扁平 PDMS 基 WTNG 的输出电压和电流分别为 30 V 和 20 μA。此外，从四层堆叠的 WTNG 在相同的压缩力下获得了平均为 170 V 和 120 μA 的非常高的电压和电流输出。值得注意的是，在超过 12000 次循环中，从多层堆叠的 WTNG 测量的输出电压没有明显差异，这证实了 WTNG 的出色机械耐久性。最后，我们仅通过我们的 WTNG 的输出功率成功地演示了发光二极管、液晶显示器和无钥匙车辆进入系统的自供电运行，而无需任何外部电源的帮助。
