摘要
近年来,随着一系列柔性可穿戴器件概念的提出及产品的应用,如何为器件提供更加安全、方便、持续的能源成为一个亟需解决的问题。自2012年摩擦纳米发电机(Triboelectric Nanogenerator,TENG)被首次报导以来,由于其具有质量轻、安全性高、清洁环保及可持续性等一系列优点,正在成为人们关注的焦点。TENG能够利用摩擦起电及静电感应原理将机械能转化为电能,利用这一特点,人们可以将行走、打字甚至呼吸、眨眼、心跳等机械能转化为电能,继而为可穿戴器件持续稳定地供电。但是,TENG也存在着能量转化效率较低、输出功率不够高、脉冲式的电信号不够稳定等不足,这也成为TENG在实际应用中亟待解决的重大难题。从材料种类、结构形貌以及混合器件3方面,综述了近几年为提高TENG输出功率、稳定性等而进行的研究进展,详细分析了不同因素对器件性能的影响。
Recent years,with the emergence and application of a series of conceptions and products of wearable electronics,it has become an urgent issue to power electronics in a safe,convenient and sustainable way. Since firstly reported in2012,triboelectric nanogenerator（ TENG） has been widely explored because of its light weight,high out-put performance,clean,sustainability,etc. The function of harvesting and transforming mechanical energy to electricity makes TENG a promising energy resource to power wearable electronic devices by turning walking,typing,even breathing and blinking to electricity. However,the disadvantages of TENG are obvious： quite low conversion,low out-put performance and impulsive out-put voltage. All these shortcomings lead to a great challenge for the application of TENG. Therefore,to improve the out-put power density of TENG has become the key factor for its application in supporting wearable electronic devices. This paper focuses on the developments of the out-put performance and stability of TENG in recent years from three aspects： 1different kinds of materials; 2structure and morphology of materials; 3hybrid nanogenenators. The influence of different factors has been analyzed in details in this paper.
