摘要

本文介绍了一种基于振动的磁能收集装置(VMEHD)。VMEHD利用压电效应和频率整流将环境中的机械能转化为电能。磁阵列使用非接触机制将输入频率校正到更高的频率。采用有限元方法对VMEHD进行了仿真。测试结果表明，输出电压在8伏~ 12伏之间，输入频率为10 Hz，整流频率为22 Hz。这提供了在机械能收集装置中获得的大功率密度。

Design, Simulation, and Fabrication of a Novel Vibration-Based Magnetic Energy Harvesting Device

In this paper, we have described a vibration-based magnetic energy harvesting device (VMEHD). The VMEHD converts mechanical energy from the environment to electrical energy by using the piezoelectric effect and frequency rectification. Magnetic arrays are used to rectify the incoming frequency to a higher frequency using non-contact mechanisms. The finite element analysis is used to simulate the VMEHD. Testing results show that the output voltage is between 8 volts to 12 volts with input frequency of 10 Hz and a rectified frequency of 22 Hz. This provides large power densities to be obtained in a mechanical energy harvesting device.
