A Novel Triboelectric Nanogenerator with High Performance and Long Duration Time of Sinusoidal Current Generation

Abstract

A triboelectric nanogenerator (TENG) composed of porous conductive-polymer and intercalated PTFE wrapping wires, is demonstrated. The proposed TENG generated a short-circuit current for a long duration and showed enhanced output performance compared with the conventional flat TENG. To qualitatively analyze the output characteristics of the proposed TENG, modeling based on parallel connection of the finite capacitors was accomplished while focusing on two important factors: surface charge density and effective surface area. Simulation was also carried out and the results were compared with the measured data to validate the proposed model.
