Abstract
The performance of cantilever piezoelectric energy harvesters using three types of piezoelectric materials, relaxor ferroelectric 0.7Pb(Mg 1/3Nb 2/3)O 3-0.3PbTiO 3 (PMN-PT) single crystals oriented along the <110> and <001> directions, and a PZT-based ceramic, were investigated. The <110> and <001> oriented PMN-PT single crystals, which have a rhombohedral phase and spontaneous polarization along the <111> direction, presented electromechanical coupling factor k31's of 0.78 and 0.42, respectively. The cantilever-type energy harvester operated by 31 resonance mode generated a larger output power of 1.07 mW for the <110> oriented PMN-PT single crystal compared to those of the other materials. The effective electromechanical coupling factor of the piezoelectric energy harvester with the <110> oriented crystal also reached 0.25, not achievable with the other piezoelectric materials. These results demonstrate that the domain engineering of the piezoelectric single crystals can provide higher design flexibility for a tiny energy harvester.
