エネルギ収穫量と圧電スキン体積を考慮したエネルギ収穫圧電スキンの形状・レイアウト設計に関する検討

Piezoelectric energy harvesting skin (EH Skin) is a device which is attached on the surface of a vibrating plate to harvest electric power. This study discusses shape/layout design of the EH skin from the view of two-objective design problem to maximize harvesting power and to minimize skin volume. Characteristics found for optimal solution are: system resonance frequency close to harmonic excitation frequency for large vibration amplitude, and second, EH skin limited for the area with large surface strain.
