Abstract

Affordable and clean energy is one of the key goals of sustainable development. Generating electrical power through materials that harness electrostatic charges through triboelectricity is a promising source of clean energy. Triboelectric nanogenetor (TENGs) are small, self-powering devices that harvest ambient mechanical energy to generate electricity through triboelectrification. Triboelectrification is a phenomenon wherein two materials of opposite electron affinity contact and separate, generating electrostatic charges of opposite polarity on the surfaces of each material. Electric field induction via a metallic electrode can harness these charges as current, creating a potential difference in powering up a device. In this study, we fabricated a compact TENG using a Vertical contact separation (VCS) design with two materials of opposite charge affinity. The TENG uses a single layer of Graphene Oxide (GO) film as the lower negatively charged material and an Indium Tin Oxide (ITO) film as the upper positively charged layer. The GiTOTENG generated a peak-to-peak open circuit voltage of 348 Volts. With an active area of 400mm2, this device generated a maximum power density of 30.34mW/m2 and a current of 0. 78μA across a load resistor of 20MQ
