  • Abstract
    Several electrostrictive materials were investigated as candidates for high frequency transducer applications. Families investigated included (1-x)Pb(Mg1/3Nb2/3)O3-(x)PbTiO 3 and PLZT relaxors, and Srand Sn-substituted BaTiO3 normal ferroelectrics. The field dependent dielectric, piezoelectric and elastic properties were characterized at frequencies between 100 kHz and 5 MHz. The large magnitude and E-field tunability of the electromechanical and elastic properties observed in several of the materials may present opportunities for several new transducer applications, such as biomedical imaging and non-destructive evaluation
