Internal electrode piezoelectric ceramic actuator

Ferroelectrics, 1983
An internal electrode multilayer piezoelectric ceramic actuator element has been investigated. An individual internal electrode has the same area as the element cross section area. It has no piezoelectric inactive part, so that it shows strain/field characteristics similar to plain piezoelectric ceramics. It can be driven by a relatively low voltage

Piezoelectric Ceramics

Journal of the American Ceramic Society, 1958
The discovery of piezoelectric effects in electrically poled barium titanate ceramic, in the early l940, was a revolutionary contribution to the electromechanical transducer art. Since then, improved barium titanate ceramics adapted to a variety of practical needs have been developed, and a number of new piezoelectric oxide‐type compounds have been ...

Analysis on coupled vibration of piezoelectric ceramic stack with two piezoelectric ceramic elements

The Journal of the Acoustical Society of America, 2019
A 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, 1990
Abstract 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

2016
Chapter 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, 1991
Porous 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, 1980
Piezoelectric 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, 1986
Abstract 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

2002
Publisher 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.
