摘　　要：摩擦纳米发电机由王中林团队2012年首次发明,是基于机械界面摩擦起电与静电感应耦合效应的新能源技术,具有轻薄、柔性、选材广的特点,可收集人体与环境中的微小机械能,不但是一个微能源产生的新方法,更是机械传感的新途径。详述了摩擦纳米发电的机理、特性与理论模型。介绍了几种提高摩擦发电性能的微纳制造方法。综述了一系列基于摩擦电的微机械传感器、执行器和自驱动微系统,及其在柔性机械、智能装备和无线传感等领域的应用研究。对摩擦电自驱动微系统目前存在的问题做出了分析与讨论,展望了其未来的研究趋势。Triboelectric nanogenerator (TENG), invented by Zhonglin WANG's group in 2012, is a new energy technology by coupling of triboelectrification and electrostatic induction between mechanical interfaces. With advantages of light weight, flexible and material diversity, the TENG can be used for harvesting human kinetic and environmental micromechanical energy, which is a new approach for not only micro power generation but also mechanical sensing. The mechanism, characteristics and theoretical model of TENG are elaborated. Several micro/nano-structure fabrication methods are reviewed for enhancing the performances of TENG A series of triboelectric microsensors, microactuators, and self-powered microsystems are summarized, as well as the application researches in flexible mechanics, intelligent equipment and wireless sensor network. The existing problems of triboelectric self-powered microsystems are discussed and the future trends are also expected.
