| Abstract: | The basic working principle of the vibration based electromagnetic energy harvester is demonstrated.The relation between the induced electromotive force,electric-magnetic damping and the harvester structure,the vibrator velocity is deduced according to Faraday's law of the electromagnetic induction.The development history and present situation of the electromagnetic energy harvester are reviewed.From the original resonant to the new type rotational harvesters in recent years,the basic structure,working pattern and their performances are classified in detail.The characteristics and suitable environment are compared for these two kinds of harvesters.According to the requirement of the maximum power output,the design considerations of the power processing circuits are analyzed,including the electric-magnetic damping,boost conversion and feedback control.Finally,the development trend of the vibration energy harvester is prospected. |
