Optimization of TriboelectricNanogenerator for Small Power Electronics

TriboelectricNanogenerators (TENGs) is a new era energy source to power portable small electronic devices. This paper presents the fabrication of vertical contact separation mode TENGs. Three different TENGs device prototypes are fabricated: (1) Kapton-Aluminium; (2) Teflon-Aluminium and (3) Room Temperature Vulcanizing (RTV)-Aluminium. To optimize the performance of TENGs the effect of various parameters such as thickness of dielectric layer, contact time between two layers and contact separation movement of layers have been observed. Experimental result demonstrates that the output voltage increases initially and then decreases with the increase in thickness of dielectric layer. It is also reported that output voltage of TENGs decreases and increases with the increase in contact time and contact separation movement respectively. In this work, an output voltage obtained from TENGs is suitable to drive applications based on small power electronics.</jats:p

Simulation and Modelling of Triboelectric Nanogenerator for Self-powered Electronic Devices

Abstract Triboelectric Nanogenerators has revolutionised the area of energy harvesting and self-powered sensing. In recent years, variety of small scale applications of triboelectric nanogenerators have been explored extensively particularly in self powered electronics, wearable and implantable devices, self-powered biosensors, human motion monitoring, location evaluation, air quality control etc. This paper discusses simulation and modelling of contact separation mode based triboelectric nanogenerator. In this work, triboelectric nanogenerators are simulated in COMSOL to compare the voltage profile of three different triboelectric materials – Kapton, Teflon and RTV Silicone with respect to Aluminium. Also, the effect of thickness of triboelectric layer on voltage profile is studied to optimize the thickness of the films. The output voltage recorded is 75 V, 60 V and 59 V for RTV Silicone, Teflon and Kapton respectively. It was observed that with increase in thickness of triboelectric layer, output voltage first increases linearly and then starts decreasing. The future research is directed towards fabricating a robust device for realising self – powered electronic devices.</jats:p
