摘要
This article reviews the history of piezoelectric perovskites and forecasts future development trends, including Uchino's discoveries such as the Pb(Mg1/3Nb2/3)O-3-PbTiO3 electrostrictor, Pb (Zn1/3Nb2/3)O-3-PbTiO3 single crystal, (Pb, La)(Zr, Ti)O-3 photostriction, and Pb(Zr, Ti)O-3-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.
