Triboelectric nanogenerator: A prominent energy solution

Abstract

The depletion of classic energy and high demand of human require the invention of novel energy source. Therefore, many of artificial energy sources had been developed. Moreover, in the era of fouth industrial revolution and speration of IoT systems, the need for high mobility and self-powered devices are strongly focused.  In 2012, a new energy convertion technology named triboelectric nanogenerator (TENG) which possess the prominent potential energy solution had been invented by Wang group (được trích dẫn trong Fan, Tian, & Wang, 2012). This nanogenerator can effectively convert wasted mechanical energy into electricity. By the cooperation of contact electrification and electrostatic induction, researcher developed four popular concepts: verticale contact mode, sliding mode, single electrode mode and freestanding mode. In this paper, a shot fundamential theory, material and application are reviewed in detail. In addition, the vertical contact mode triboelectric generator using commercial PVC and aluminum nanofiber films was investigated. The output signal gives positive results with a voltage of 31.7V and a current of 6.2µA at an external force of 10N.
