ABSTRACT: To help address global warming, various power generation methods that do not release carbon dioxide have been established, including electrostatic power generation. A wide variety of electrostatic generators have been proposed for many centuries; however, the vibration-type electrostatic generator is currently the most commonly utilised. Electricity is generated via the movement of a charge carrier, which is charged by electrostatic induction in opposition to an injection electret (Hereafter, this will be abbreviated as IE.). The carrier is displaced from the electret using external energy forms such as waves, and the resultantly generated charge is allowed to flow. As IE and charge carrier are charged with opposite polarities, a strong Coulomb force is generated between them, which acts as a braking force against the movement of the carrier. Therefore this paper present an improved method that revealed this braking force can be eliminated by placing a counter-electret (Hereafter, this will be abbreviated as CE.)—charged with the opposite polarity—adjacent to IE.
