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.
