Abstract
The aim of this study is to optimize the electromagnetic vibration energy harvesters with typical cylindrical shape considering the aspect ratio. In the optimization procedure, voltage and power, which are two key factors of energy harvesting systems, are mainly considered in the three types of electromagnetic vibration energy harvester according to various aspect ratios. We then investigate the optimum design parameters in each case. The results show that there is an optimum aspect ratio that maximizes the output voltage and power for the same volume. We also find that the optimum design parameters for each aspect ratio have a relatively constant value regardless of the aspect ratio. An experimental study is also conducted to verify the simulation results of the design optimization, and it clearly confirms that the proposed optimization result matches the experimental results well.
