Abstract :
Energy scavenging research shows a growing interest these last years. This paper describes all the potential energy losses in an energy harvesting device. Such a micro power generator may be used as a mechanical to electrical energy transformer. A finite element piezoelectric optimization is performed on a cantilever structure and enables to show the best location for the piezoelectric plate.
