Piezoelectric Micromechanical Energy Harvesters
MetadataShow full item record
The present invention comprises systems, apparatuses, and methods for harvesting ambient mechanical energy at a lower frequency and transforming the harvested energy into electrical energy at a higher frequency. Transforming the energy from relatively lower input frequency energy to relatively higher output frequency energy can help realize greater efficiencies found at higher frequencies. Because the input plane of the ambient mechanical energy is not always predictable, some embodiments of the present invention comprise both in-plane and out-of-plane energy harvesters that produce an electrical output in multiple planes.
