CERAMICS WITH RELAXOR FERROELECTRIC FOR HARVESTING PZT ENERGY CAPABLE OF IMPROVING FIGURE OF MERIT

摘要

PURPOSE: Ceramics with relaxor ferroelectric for harvesting PZT energy are provided to easily apply piezoelectric materials for energy harvest by adding the relaxor ferroelectric to the piezoelectric materials.;CONSTITUTION: Ceramics include relaxor ferroelectric, PZN-PZT piezoelectric ceramics, and PCN-PZT piezoelectric ceramics. The relaxor ferroelectric changes composition sensitivity of piezoelectric materials by substituting a part of a lattice structure of PZT based piezoelectric materials. The ceramics are used for harvesting energy. The relaxor ferroelectric of 30 to 50 % is included in the ceramics.;COPYRIGHT KIPO 2012
