摘要:

近年來，隨著一系列柔性可穿戴器件概念的提出及產品的應用，人們發現如何為器件提供更加安全、方便、持續的能源成為一個亟需解決的問題。自從2012年摩擦納米發電機(Triboelectric nanogenerator，TENG)被首次報導以來，由于其具有的質量輕、安全性高、清潔環保及可持續性等一系列優點，正在成為人們關注的焦點。TENG能夠利用摩擦起電及靜電感應原理將機械能轉化為電能，利用這一特點，人們可以將行走、打字甚至呼吸、眨眼、心跳等機械能轉化為電能繼而對可穿戴器件持續穩定地供電。但是，TENG也存在著能量轉化效率較低、輸出功率不夠高、脈沖式的電信號不夠穩定等不足，這也成為TENG實際應用中的重大難題。本文將從材料種類、結構形貌以及混合器件這三個方面，綜述近幾年為提高TENG輸出功率、穩定性等而進行的研究進展，詳細分析不同因素對器件性能的影響。

Abstract:

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 in 2012, 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: 1. Different kinds of materials; 2.Structure and morphology of materials; 3. Hybrid nanogenenators. The influence of different factors has been analyzed in details in this paper.
