title: Glory of piezoelectric perovskites.
abstract: This article reviews the history of piezoelectric perovskites and forecasts future development trends, including Uchino's discoveries such as the Pb(Mg1/3Nb2/3)O3-PbTiO3electrostrictor, Pb(Zn1/3Nb2/3)O3-PbTiO3single crystal, (Pb, La)(Zr, Ti)O3photostriction, and Pb(Zr, Ti)O3-Terfenol magnetoelectric composites. We discuss five key trends in the development of piezomaterials: performance to reliability, hard to soft, macro to nano, homo to hetero, and single to multi-functional.
