Abstract

The high power characteristics of various piezoelectric ceramics and 1-3 composites were investigated. In contrast to hard Pb(Zr,Ti)O 3, modified (Bi 0.5Na 0.5)TiO 3 based ceramics were found to show a relatively linear electromechanical response under high drive conditions due to their high stability of mechanical quality factor. The effects of high drive field and duty cycle on the behavior of 1-3 composites were analyzed by varying active and passive components. Improved high power characteristics of 1-3 composites were achieved by selection of optimized composite components, with enhanced electromechanical efficiency and thermal stability under high drive conditions.
