Rotary freestanding ternary electrification layered triboelectric nanogenerator (Tel-Teng) for micro vertical axis wind turbine (VAWT)

Abstract

The triboelectric nanogenerator (TENG) harvests ambient mechanical energy and converts it into electricity. TENGs can function through the triboelectrification mechanism. These contact electrifications will begin with a source of continuous mechanical motion. The wind is a renewable resource that can provide this continual mechanical motion. Wind turbines capture wind energy and use it to generate rotational mechanical energy. The rotary freestanding triboelectric layer-based TENGs utilize this. The output of freestanding TENGs has improved with ternary electrification layered-triboelectric nanogenerators (TEL-TENG). This study integrates the freestanding rotary TEL-TENG into any microscale vertical axis wind turbine (VAWT) that will allow power generation. It can use to run low-power devices. It utilizes Copper, FEP, and Kapton, which have promising properties as triboelectric materials. The prototype underwent thorough testing at different wind speeds in urban areas to prove its effectiveness. It yielded a minimum power of 4.396 mW at one (1) m/s wind speed and a maximum power of 523.8 mW at five (5) m/s wind speed and efficiencies with a minimum value of 27% at four (4) m/s wind speed and a maximum value of 46.63% at three (3) m/s wind speed.
