Methodology For Design of Broadband Low Frequency Piezoelectric Energy Harvester
A significant impediment in the deployment of vibration-based energy harvesting devices has been the limitation that most of the low frequency transducers, usually in the form of unimorph or bimorph cantilever beams, extract energy in a very narro bandwidth around the transducer's fundamental frequency. In such devices, slight deviation from the fundamental...
