In this paper an important figure of merit is introduced and discussed with reference to electromagnetic vibration energy harvesters which are loaded by diode bridge rectifiers. It is called Harvester Ideal Utilization Factor. It precisely quantifies how close to the optimum the harvester is loaded. Such a figure of merit can be defined not only for electromagnetic but also for piezoelectric harvesters as long as the assumptions which allow the modeling of such vibration harvesters by means of an equivalent linear electric circuit are valid.

Abstract
In this paper an important figure of merit is introduced and discussed with reference to electromagnetic vibration energy harvesters which are loaded by diode bridge rectifiers. It is called Harvester Ideal Utilization Factor. It precisely quantifies how close to the optimum the harvester is loaded. Such a figure of merit can be defined not only for electromagnetic but also for piezoelectric harvesters as long as the assumptions which allow the modeling of such vibration harvesters by means of an equivalent linear electric circuit are valid.File in questo prodotto:
