title = "A Bistable piezoelectric energy harvester for broadening frequency bandwidth",
abstract = "A bistable energy harvester is proposed. It consists of cantilever couples, permanent magnets, as well as the intermediate slot, which can make cross beam accomplish horizontal movements to acquire two states. Each state corresponds to two bistable. Under external excitations, adjust the cross beam position to realize two states switch to acquire four bistable state. Because of this will broaden the frequency bandwidth and thus increase the harvested energy, which is expected to be applicable to self-powered lateral vibration sensor devices. After the simulation analysis, the energy collected by this part was improved by 193\%. The bandwidth of the two subsystems corresponding to each state is widened by at least 20 Hz.",
