The ideal utilization factor: A tool to optimize the energetic performances of resonant electromagnetic vibration energy harvesters

Abstract

In this paper, the Ideal Utilization Factor (IUF) is presented and discussed with reference to Resonant Electromagnetic Vibration Energy Harvesters (REVEHs). The IUF is an important figure of merit that allows the identification suitable additional non-dissipative components to insert between the REVEH coil and the bridge rectifier. Such components allow improving the actual energetic performances of REVEHs in the frequency regions of practical interest.
