Demonstration of Non‐contact Out‐of‐Plane Vibration Energy Harvesting Using an Electric‐Double‐Layer Electret

Abstract

This paper reports demonstration results of non‐contact out‐of‐plane vibration energy harvesting using an electric‐double‐layer electret (EDLE). Unlike contact types or non‐contact in‐plane types, the proposed operation type can be useful in terms of expanding the operating frequency range and simplifying the device structures. A demonstration system is developed, and power generation is confirmed using an EDLE with a surface potential of −1 V under an atmospheric condition. © 2023 Institute of Electrical Engineers of Japan.
