A 3-way pushable electret-based energy harvester fabricated with 3d-printing and PDMS molding

Abstract

An energy harvester device is developed with a PDMS chamber that contains upper and bottom electrodes (Al foil and electret) to form an air-dielectric variable capacitor, which can be pushed in three different manners to generate power through the up-and-down motion of the PDMS membrane. The 3-way mechanisms are experimentally compared.
