本文提出了一种利用压电元件的能量收集技术，压电元件是一种将机械能转换为电能的发电机。在这项研究中，低频特性的压电陶瓷型驱动器进行了实验研究。使用悬臂梁的优点是可以进行非常大的位移并提高PZT元件的耐久性。分别对150[mm]×20[mm]×1.5[mm]、170[mm]×20[mm]×1.5 [mm]、190[mm]×20[mm]×1.5[mm]、210[mm]×20[mm]×1.5[mm]四种悬臂梁进行了实验，悬臂梁材料为铝合金。悬臂梁与压电双晶片型驱动器被固定在振动器。研究了悬臂梁端部0[g]、2.22[g]、4.34[g]、5.87[g]、8.66[g]、11.01[g]的频率和质量变化特性。
This paper presents an energy harvesting technique using the piezoelectric element that is a kind of generator which converts the mechanical energy to the electric one. In this study, low frequency characteristics of the cantilever-type piezoelectric actuator were experimentally investigated. Advantages of the cantilever use are to take a very large displacement and to improve the endurance of the PZT element. Four kinds of cantilever which sizes are 150[mm]×20[mm]×1.5[mm], 170[mm]×20[mm]×1.5[mm], 190[mm]×20[mm]×1.5[mm], 210[mm]×20[mm]×1.5[mm] and the material of cantilever is an aluminum were experimented, respectively. The cantilever with a bimorph type PZT actuator was fixed on the vibrator. The characteristics of frequency and mass variation of cantilever end part such as 0[g], 2.22[g], 4.34[g], 5.87[g], 8.66[g], 11.01[g] were investigated.
