Abstract

Due to its large piezoelectric and electrostrictive responses to an applied electric field the ( 1 𝑥 )Pb(Mg1/3Nb2/3)O3 𝑥 PbTiO3 (PMN-PT) solid solution has been widely investigated as a promising material for different actuator applications. This paper discusses some of the recent achievements in the field of PMN-PT piezoelectric and electrostrictive actuators manufactured from PMN-PT single crystals, bulk ceramics, or thick films. The functional properties of PMN-PT materials and some representative examples of the investigated PMN-PT actuator structures and their applications are reported.
