我们报告了一种制造简单、性能卓越且经济高效的摩擦纳米发电机（TENG），它基于聚二甲基硅氧烷（PDMS）薄膜和聚对苯二甲酸乙二醇酯（PET）薄膜之间的循环接触分离，可有效收集脚步能量。弹性海绵首先被用作TENG中的间隔物，其中间隔物的尺寸和厚度对TENG的输出性能有显着影响。通过使用优化的设备，基于TENG的鞋垫用于收集人体行走能量，最大输出电压和电流密度分别达到220 V和40 μA。我们还证明，使用单层 TENG 制成的鞋垫可以直接用于点亮串联的 30 个白色发光二极管 (LED)。凭借这种简单的制造、出色的性能、强大的特性和低成本技术的优点，我们相信 TENG 不仅可以为小型电子设备提供动力，而且还可以通过工程设计为大规模能量收集做出贡献。 (C) 2013 Elsevier Ltd. 保留所有权利。
We report a simple fabrication, great performance and cost-effective triboelectric nanogenerator (TENG), which is based on the cycled contact-separation between a polydimethylsiloxane (PDMS) film and a polyethylene terephthalate (PET) film, for effectively harvesting footfall energy. The elastic sponge is first used as the spacer in the TENG, where the size and the thickness of the spacers have a significant effect on the output performance of the TENG. By using the optimized device, a TENG-based shoe insole is used to harvest human walking energy, where the maximum output voltage and current density reached up to 220 V and 40 mu A, respectively. We also demonstrate that the fabricated shoe insole using a single layer of TENG can be directly used to light up 30 white light-emitting diodes (LEDs) in serial connection. By taking the merits of this simple fabrication, outstanding performance, robust characteristic and low-cost technology, we believe that TENG can open up great opportunities not only for powering small electronics, but also can contribute to large-scale energy harvesting through engineering design.
