用于可穿戴电子设备的可拉伸摩擦电纳米发电机（TENG）在自供电能量收集和存储设备领域具有显著的需求。设计合适的电极是开发完全可穿戴TENG设备的主要挑战之一，需要进行旨在探索新材料和方法以开发可拉伸电极的研究。这篇综述文章致力于介绍探索柔性TENG新材料的最新进展，特别强调可穿戴设备的电极组件。此外，材料，可以提供潜在的性能，如透明度，自我修复性和防水性也进行了审查。还讨论了固有可拉伸材料以及软质和刚性材料的组合，包括聚合物及其复合材料，无机和陶瓷材料，2D材料和碳质纳米材料。此外，还探索了用于设计可穿戴TENG设备的高度可拉伸电极的各种制造策略和几何图案化技术。讨论了目前方法所面临的挑战以及未来发展的可行性建议。可穿戴TENG组件的一般要求示意图。
Stretchable Triboelectric Nanogenerators (TENGs) for wearable electronics are in significant demand in the area of self-powered energy harvesting and storage devices. Designing a suitable electrode is one of the major challenges in developing a fully wearable TENG device and requires research aimed at exploring new materials and methods to develop stretchable electrodes. This review article is dedicated to presenting recent developments in exploring new materials for flexible TENGs with special emphasis on electrode components for wearable devices. In addition, materials that can potentially deliver properties such as transparency, self-healability and water-resistance are also reviewed. Inherently stretchable materials and a combination of soft and rigid materials including polymers and their composites, inorganic and ceramic materials, 2D materials and carbonaceous nanomaterials are also addressed. Additionally, various fabrication strategies and geometrical patterning techniques employed for designing highly stretchable electrodes for wearable TENG devices are also explored. The challenges reflected in the present approaches as well as feasible suggestions for future advancements are discussed. Schematic illustration of the general requirements of components of a wearable TENG.
