Abstract

High performance electroactive materials were studied as the driver element for the 'cymbal' flextensional transducer. The compositions included were commercially available Navy Type I and PK1552 lead zirconate titanate (PZT) piezoceramic, relaxor lead magnesium niobate-lead titanate (PMN-PT) ceramic, lead zinc niobate-lead titanate (PZN-PT) single crystal, and lead lanthanum stannate zirconate titanate (PLSnZT) ceramic with antiferroelectric to ferroelectric transitions. Displacement amplifications from 14× to 50× were found for various cymbal configurations. The influence of material properties, cymbal design, and drive signal on the displacement amplification factor is discussed.
