Abstract
In general, existed vibration energy harvester is optimum in electronic energy gleaned from vibration energy with fixed single frequency, because it is using resonance. But it is limit in electronic energy gleaned from ocean wave energy with variant frequency. This paper studied for width band vibration energy harvester that obtains electronic energy from ocean wave with infinite vibration energy in order to solve it. It is composed of buoy to occur resonance in the center frequency of ocean wave energy and the vibration system to occur resonance in the same frequency. As a result, existed vibration energy harvester using resonance maximized electronic energy conversion efficiency in single frequency, while proposed width band vibration energy harvester has merit that maximized electronic energy conversion efficiency in ocean wave with variant frequency.
