Enhanced Performance Triboelectric Nanogenerator With Strach Biopolymer Composite Interface Layer

Triboelectric nanogenerator is a potential mechanical energy conversion technology developed for future energy conversion. The increase in TENG output power is affected by the dielectric film. In addition, the damage to the surface of the film becomes an obstacle to increasing the output power. In this study, we propose the structure of Composite Biopolymer Electrolytes which is an activation method of increasing the contact surface interface to maximize the output performance of TENG.
