Driving Characteristics of a ¥è–Type Piezoelectric Generating Device for Energy Harvesting
Dr.Seongsu Jeong
Changwon National University
A newly ¥è-type piezoelectric generating device that improved from existing cymbal-type piezoelectric generating device was proposed. Generating device was designed by clamping the both ends of plate ceramic using elastic bodies and it convert the vibrations or pressure to horizontal displacement. ¥è-type generating device has advantages of cymbal-type generating device that have low influence on resonance frequency and high durability. And also it improved generating efficiency and high sensibility despite light vibrations. Optimized model was selected by simulating the proposed device using FEM and the results was confirmed through the fabrication and experiments. In this paper, the characteristics of the generating device were determined by setting the parameters such as size and angles of ceramics and elastic bodies.
