摘要

本文提出了一种宽带电磁振动发电装置，它能有效地清除能量，并在预定的频率范围内产生稳定的功率。电力是通过电磁感应产生的，在谐振悬臂梁的顶部使用磁铁和线圈。所述发生器通过实现若干不同长度的串联悬臂梁，覆盖了较宽的外部振动频率范围。该装置在3.3 ~ 3.6 kHz的外部振动下，以20 mV电压产生0.5 muW的连续功率。

A Wideband Electromagnetic Micro Power Generator for Wireless Microsystems

This paper presents a wideband electromagnetic (EM) vibration-to-electrical power generator which can efficiently scavenge energy and generate steady power over a predetermined frequency range. Power is generated by means of electromagnetic induction using a magnet and coils on top of resonating cantilever beams. The reported generator covers a wide band of external vibration frequency by implementing a number of serially connected cantilevers in different lengths. The device generates 0.5 muW continuous power with 20 mV voltage between 3.3 and 3.6 kHz of external vibration.
