摘要
压电材料在外力的作用下可以产生电荷,将这部分电荷收集起来可以为微功率电器提供电能。在对单层悬臂梁压电发电装置进行实验研究的基础上,设计并制作出多层悬臂梁压电发电装置;对两种装置的实验结果进行研究分析,不仅拓宽了悬臂梁压电发电装置的谐振频带,更有效地提高了其发电能力。
Piezoelectric material can generate power under the action of external force.The power can be collected to provide to wireless communication systems.On the basis of experimental study on power-generating capacity for single-deck piezoelectric cantilever,multiple piezoelectric cantilevers are manufactured.Compared with single-deck piezoelectric cantilever,the multiple piezoelectric cantilevers can increase the band of resonance frequency and effectively improve the power-generating capacity.
