越来越多的人需要利用我们周围的能量，这使得研究人员深入研究从我们的环境中生产绿色能源的概念。纺织品和可穿戴摩擦电纳米发电机（t-TENG或w-TENG）是这方面有前途的选择。纺织品和可穿戴摩擦电纳米发电机可以使用改性纺织品材料或替代基础材料（如聚酯、PDMS、硅树脂等）将织物运动中存在的机械能转化为电能。这些设备旨在安装在衣服上或直接安装在皮肤上，使其高度便携，但也可以安装在存在机械能的任何其他区域（鞋，地板，袋包装等）。它们已被证明能够产生足够的能量来为一些低功耗设备和传感器供电。纺织TENG的一个关键限制是与基于非纺织膜的TENG相比其输出低。在这篇综述中，我们反映了通过界面改性提高纺织TENG性能的任务。具体而言，该文件调查，已通过使用不同的金属或金属氧化物和等离子体工艺的纺织品的表面改性可能的改进。最后，从摩擦学和接触力学的角度强调了一些关键领域，这些领域可能有可能导致性能的进一步显著增强;即，设计织物界面以提高接触面积。
An increasing need to harness power from our surroundings has led researchers to delve into the concept of green energy production from our environment. Textile and wearable triboelectric nanogenerators (t-TENGs or w-TENGs) are a promising option in this regard. Textile and wearable triboelectric nanogenerators can convert mechanical energy present in fabric movements into electrical power using modified textile materials or alternative base materials (such as polyester, PDMS, silicone, etc.). These devices are intended to be mounted on garments or directly on the skin making them highly portable, but could also be installed in any other areas where mechanical energy is present (shoes, floor, bag packs etc.). They have been proven to be capable of generating sufficient energy to power some low power devices and sensors. A key present limitation for textile TENGs is their low output compared to non-textile film based TENGs. In this review, we reflect on the task of boosting textile TENG performance via interface modification. Specifically, the paper surveys the improvements that have been possible via surface modification of textiles using different metals or metal oxides and plasma processes. Finally, some key areas are highlighted from a tribology and contact mechanics perspective that may have the potential to lead to further significant enhancements in performance; namely, designing fabric interfaces to boost contact area.
