Summary:Vibration energy harvesting devices have been widely used to power many electronic self-sustainable devices. The aim of this study is to introduce an alternative design to an existing electromagnetic energy harvesting devices to improve the power production of the unit. This thesis presents a multiple degree of freedom compared design and it has demonstrated higher power efficiency over a wider range of frequencies. The power outputs for both the previous single degree of freedom and the current designs are compared and the developed models are validated against their experimental values. Finally, the numerical model is used to find an optimal arrangement to produce the maximum power for the unit.
