A Novel Integrated MWCNTs/PDMS based Flexible Triboelectric Nanogenerator

Abstract

A novel integrated multi-wall carbon nanotube /polydimethylsiloxane (MWCNTs/PDMS) and Polyvinylidene Fluoride (PVDF) based flexible triboelectric nanogenerator (TENG) was fabricated for energy harvesting application. The TNEG consists of minimal parts: aluminium (AI) electrode, PVDF layer and MWCNTs/PDMS layer. A surface roughness and thickness of −0.45 µm was measured for the fabricated MWCNT/PDMS respectively. The capability of the TENG in term of open circuit voltage (OCV) and short circuit current (SCC) was investigated by subjecting it to a force of 5 N, 10 N and 15 N at varying frequencies of 3 Hz, 5Hz and 7 Hz respectively. The maximum OCV of 21.6 V and SCC of 1.7 µA was obtained for an applied force of 15 N at frequency 7 Hz, respectively.
