Abstract
Recent developments in triboelectric nanogenerators (TENG) make self-powered sensors possible and realistic by harvesting waste mechanical energy from the environment. This paper focuses on brief introduction on the basic principles and various working modes of TENGs, theoretical study and numerical analysis on TENGs in contact and sliding working modes. Numerical analysis is conducted using MATLAB for KAPTON-PMMA (Poly(methyl methacrylate)) TENG models, working on sliding mode and contact mode. The dynamic output characteristics of sliding mode TENG are evaluated with the varying input resistance value and dielectric gap distance.
