摘要
从振动能量采集器的低频、高功率特点出发,分析了电磁式、磁电式、静电式、压电式这四种结构的优缺点。详细介绍了这些振动能量采集器的发展现状与趋势,并比较了它们的性能与实用性。压电式振动能量采集器的研发时间最早,各项性能参数较均衡。设计时可以优先选择压电式振动能量采集器。
Vibration energy harvesters can collect the external vibration energy and convert it into electric energy to load the devices.Four types of vibration energy harvesters with different operation modes were introduced in terms of low frequency and high power.They were electromagnetic,magnetostrictive,electrostatic and piezoelectric vibration energy harvesters.The advantages and disadvantages of the four different structures were analyzed.Meanwhile,the development status and trend of these vibration energy harvesters were introduced in detail.Then their performances and practicability were compared.Among them,piezoelectric vibration energy harvester was studied first,it had nice and uniform performances.It was the first choice in the design of vibration energy harvesters.
