Experimental Determination of Piezoelectric Parameters.
Abstract
A theory was developed whereby the elastic compliance, piezoelectric constant and dielectric constant could all be determined by mechanically driving a transversely polarized ceramic bar. 3-port analysis was applied to longitudinal vibrations in a transversely polarized ceramic bar. Furthermore, losses were accounted for by assuming complex dissipation. Experimentation was conducted according to the developed theory using standard 3-port techniques. The zero velocity boundary condition was approximated by using quarter-wavelength glass rods. Barium titanate and lead zirconate titanate were investigated for the two to four kilohertz audio frequency band and for driving levels ranging from ten to fifty g's. (Author)
