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. Method of doping starch biopolymer matrix with metal oxide TiO2. The doping effect of TiO2 nanoparticles increases physical resistance, increasing surface roughness which allows air voids between the two contact surfaces during electrification contact. The results showed that the starch-TiO2 textbf electrolyte biopolymer composite film had a rougher surface than the starch film with Ra values of 380 nm and 195 nm and Rq 495 nm and 250 nm, triboelectrification process is improved with an output performance effect of 170 mW.m-2 © 2021 IEEE.
