摘要
为了了解利用人体运动能量给柔性可穿戴电子设备持续供电的现状,通过回顾国内外纺织基摩擦纳米发电机的最新研究成果,详细阐述了纤维基摩擦纳米发电机在单电极模式下发电的基本原理;从摩擦纳米发电机的类型和制备方法等方面,归纳和总结了目前纤维基摩擦纳米发电机最典型的双螺旋和同轴鞘芯结构和各自发电性能;指出了目前采用涂层、机织、针织和静电纺丝等方法制备的纺织基摩擦纳米发电机的特点,及其在收集人体机械能方面的优势、不足和改进方法;最后总结出可以采用现代化织造技术来提高纺织基摩擦纳米发电机的生产效率,以及其他提高发电效率的思路。
To understand the current situation of powering flexible and wearable electronics by converting mechanical energy from human bodies into electricity, the latest studies of textile-based triboelectric nanogenerators (TENGs) worldwide were comprehensively reviewed. The basic mechanism of single electrode mode TENGs were interpreted in details. According to different types and preparation methods of TENGs, the fiber-based TENGs could be divided typically into double helix structure and coaxial structure, of which the electrical output performance was also discussed. Besides, the properties of textile-based TENGs prepared by using coating, weaving, knitting and electrospinning were pointed out. Meanwhile their advantages, disadvantages and corresponding optimizing methods in collecting mechanical energy from human body were put forward. Finally, the summary was made that modern weaving technology could significantly improve the productivity of textile- based TENGs and other thinking to improve the power generation efficiency was given.
