Analysis on coupled vibration of piezoelectric ceramic stack with two piezoelectric ceramic elements
The Journal of the Acoustical Society of America, 2019A longitudinally polarized piezoelectric ceramic stack with two piezoelectric ceramic elements is an important part of sandwich piezoelectric transducers. The three-dimensional coupled vibration of piezoelectric ceramic stack is analyzed. Since the longitudinal and radial dimensions of particular piezoelectric ceramic stacks are approximately equal ...

Piezoelectric relaxation studies of ferro-piezoelectric ceramics
Ferroelectrics, 1990Abstract Measurements of amplitude and phase of the delivered piezoelectric current as a function of frequency and temperature were performed. The studied materials were ferro-piezoelectric ceramics of the PZT family and Calcium Modified Lead Titanates.

Piezoelectric Ceramic Materials
2016Chapter is devoted to the specific material symmetry of ferroelectric ceramics. Fundamental ferroelectric properties of ceramics like texture, electric poling, hysteresis loop and operational limits are briefly described. Material properties of PZT ceramics are discussed in more details including material data for some of the commercially available ...

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.
