Paper Abstract

The field of renewable energy has recently taken a surge with the advent of power harvesting systems. Much of the work previously done has focused primarily on dipole materials such as piezoelectric generators due to their high energy density. Exploring other vibration conversion techniques, electromagnetism has been theorized to be highly viable as well. In fact, in the presence of strong magnetic fields, its energy density can exceed that of piezoelectric systems. The key aspects to its usefulness lie in maximizing the rate of change of magnetic flux and thus maximizing the electric potential from the electromotive force. The specifics of this research include the descriptions of the electromagnetic theory, fabrication, and performance of a micro-electromagnetic power harvester with a vibration energy source. In addition, an empirical analysis of the influence of the micro-coil's geometry on the performance of the MEMS power harvester is given.
