Porous Piezoelectric Ceramic Transducer
Japanese Journal of Applied Physics, 1991Porous piezoelectric ceramics of Pb(Zr, Ti)O3, (P-PZT), have been newly developed to apply to transducers in an echo sounder. The P-PZT was prepared from a mixture of PZT and poly-methyl-methacrylate (PMMA) powders. The piezoelectric characteristics of the P-PZT such as the dielectric constant (ε), voltage output constant (g constant), acoustic ...

Piezoelectric ceramics: Characteristics and applications
The Journal of the Acoustical Society of America, 1980Piezoelectric ceramics have been used for a little over 30 years. The first piezoelectric ceramic was barium titanate and it is still used. The lead titanate zirconate ceramics were introduced about 1955 and quickly became the most widely used piezoelectric material.

Monolithic multilayer piezoelectric ceramics
Ferroelectrics, 1986Abstract Multilayer piezoelectric ceramics promise to close the gap between the high electric field strengths required to generate the largest possible deformation in piezoelectric ceramics and the low supply voltages (5 V to 15 V) conventional in present-day electronics.

Fracture of piezoelectric ceramics
2002Publisher Summary Piezoelectric ceramics can sense and actuate by rapidly converting mechanical and thermal signals into electrical ones, the reverse also being true. The piezoelectric properties and quick response characteristics have made piezoelectric ceramics one of the most commonly used smart materials.

Piezoelectric ceramic compositional development
The Journal of the Acoustical Society of America, 1989The original piezoelectric ceramic material was unmodified barium titanate. It was little used except as compositionally modified. The earliest work was by W. P. Mason and this led to improved characteristics for sonar transducers and then to phonograph cartridge applications.

Alkali Niobate Piezoelectric Ceramics
2011Piezoelectric ceramic materials are widely used in various electronic equipments [1–26]. Lead-based perovskite materials such as Pb(Ti, Zr)O3 (PZT), or PbTiO3-based materials are commonly used there. Piezoelectric properties of these lead-containing materials have been studied by a large number of researchers. On the other hand, environmental conscious

Nonlinearity in piezoelectric ceramics
Journal of Materials Science, 2001The paper presents an overview of experimental evidence and present understanding of nonlinear dielectric, elastic and piezoelectric relationships in piezoelectric ceramics. This topic has gained an increasing recognition in recent years due to the use of such materials under extreme operating conditions, for example in electromechanical actuators and ...
