Abstract
Our work aims to develop a vibration generator that generates electrical energy from surrounding mechanical vibrations. This generator represents an alternative to powering wireless sensors without using primary batteries. The generator is an electromagnetic induction generator. When the generator is excited by ambient vibration, the resonant mechanism induces the relative motion of the magnetic circuit relative to the copper coil. This relative motion generates voltage across the coil due to Faraday's laws. This energy harvesting technology has advantages over conventional types concerning size and efficiency, and it is incredibly robust and has low electrical impedance. The generator model can be excited by sine, random, or actual vibration data, and can be easily scaled up to increase the output power in order to generate an expected output power.
