The present invention relates to an energy harvester device comprising a plurality of elongate resonator beams. The resonator beams include a piezoelectric material extending between first and second ends. One or more bases are connected to the first end of each of the resonator beams, with the second end of the resonator beams being freely extending from the one or more bases as a cantilever. A mass is attached to each of the second ends of the resonator beams. Each of the resonator beams is tuned to a resonant frequency offset relative to each of the other resonator beams by 0.1/W to 0.9/W, wherein W is a temporal width between a first impulse and a second impulse which excite motion of the resonator beams. Also disclosed is a system comprising an apparatus and the energy harvester device, as well as methods of using and designing the system.
