Abstract
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.
Highlights
Energy plays a vital role which defines the caliber of our life and sustainable growth of modern society
All devices show a linear rise in the output voltage on increasing the thickness of dielectric layer from 0.4 mm to 0.12 mm
On further increasing the thickness of dielectric layer from 0.12mm to 0.2 mm a downward trend is visible which is less predominant in case of Kapton-Al TENG based device
Summary
Energy plays a vital role which defines the caliber of our life and sustainable growth of modern society. Researchers have extensively studied nanogenerators based on different mechanical or thermal energy harvesting techniques such as piezoelectric, triboelectric, and pyroelectric Out of all these techniques, triboelectricnanogenerators are most effective in generating electricity from mechanical energy such as human body motion, vibrations , rain droplets and winds [1,2,3,4,5]. All the modes of TENG require two different materials with opposite electron affinity and atleasttwo electrode connection which are separated from each other. They are widely used for the selfpowered systems with high-voltage requirements [11]. Their performances are analysed by varying the thickness of the dielectric layers, contact time between two layers and contact separation movement of layers
