Wideband capacitive energy harvester based on mechanical frequency-up conversion

A novel mechanical frequency-up convertor for energy harvesting using low frequency ambient vibration based on overlapping capacitive comb has been proposed in this paper. Centrally clamped bistable beam is used to frequency-up conversion which is similar to pre-buckled structure and makes a large a...

More Information
Summary:A novel mechanical frequency-up convertor for energy harvesting using low frequency ambient vibration based on overlapping capacitive comb has been proposed in this paper. Centrally clamped bistable beam is used to frequency-up conversion which is similar to pre-buckled structure and makes a large acceleration to induce initial displacement. We have achieved more average power from the proposed system by excitation at the low frequencies so improved power density.
