Performance Characteristics of Vibration Energy Harvesting Using [001] and [011]-Poled PMN-PZT Single Crystals

[001] 및 [011] 방향 분극의 압전 단결정 PMN-PZT 를 이용한 진동 에너지 수확 특성

This work investigated the electromechanical performance of a cantilevered vibration energy harvester incorporating the single crystal PMN-PZT, manufactured with the most recent technology of solid-state single crystal growth. Single crystal PMN-PZTs with two different crystallographic axes such as [011] and [001] were considered. For the [011] orientation, because material properties such as the stiffness, piezoelectric strain coefficients are not the same in the directions normal to the crystallographic axis, the effects of the transversely anisotropy on the magnitude and frequency bandwidth of output power were also analyzed.
