摘要
针对环境振动源的多样性,对环境适应型压电振动发电微电源的发展进行了回顾,对各种类型压电振动发电微电源的性能进行了分析和总结。在现有环境适应型压电振动发电微电源的基础上,提出了一种新颖的环境适应型压电振动发电微电源结构,该结构能够敏感多个方向振源的振动且能够在较宽的频率范围内收集到较多的能量。指出了环境适应型压电振动发电微电源在进一步发展中需要解决的问题,压电振动发电微电源作为一种绿色新能源装置,随着研究的不断深入,必将带来良好的应用前景。
In order to realize the purpose of multi-direction environmental vibration energy harvesting, the development of ambient adaptation type piezoelectric vibration micro power generators is reviewed, and the performance of the piezoelectric vibration micro power generators is analyzed and summarized. A novel ambient adaptation type piezoelectric vibration micro power generator is proposed based on the existing piezoelectric vibration micro power generators. The micro power generator can be sensitive to more than one direction vibration of the vibration source and can harvest more energy within a wider frequency. The problems in the development of the micro power generators are pointed out. The piezoelectric vibration micro power generators are green energy devices, and they will bring us a good application prospect.
