Abstract :
This paper presents a low cost solution for energy harvester based on a bistable clamped-clamped PET (PolyEthyleneTerephthalate) beam and two piezoelectric transducers. The beam switching is activated by environmental vibrations. The mechanical-to-electrical energy conversion is performed by two piezoelectric transducers laterally installed to experience beam impacts each time the device switches from one stable state to the other one. Main advantages of the proposed approach are related to the wide frequency band assuring high device efficiency and the adopted low cost technology.
