Potential-Based Design of Electret-Dielectric Elastomer Laminated Energy Harvester

This paper presents a design method for an electrostatic energy harvester, constructed by laminating an electret and a dielectric elastomer. The proposed design method is based on a static analysis of the electrostatic potential of the harvester. The calculation results showed strong agreement with dynamic simulation results, suggesting that the proposed method could be a substitute for dynamic simulation with a low computational cost. Validation experiments indicated that the proposed method is effective for design optimization of the thicknesses of the electret and the dielectric elastomer in the harvester.
