Facile synthesis and high d33 of single-crystalline KNbO3 nanocubes

Chemical Communications, 2008
Single-crystalline KNbO(3) nanocubes with orthorhombic phase were prepared in a large scale by a simple one-step molten salt route without using any surfactant as template; the nanostructures exhibited high piezoelectric properties such as d(33)=105 pC/N and k(p)=0.34 as piezoelectric materials.

0–3 Piezoelectric composite film with high d33 coefficient

Sensors and Actuators A: Physical, 1998
Abstract This paper reports the influence of solvent treatment on the behaviour of 0–3 piezoelectric composite films. In our experiments, 0–3 composite piezoelectric films are prepared and treated in a solvent for a period of time, and their piezoelectric properties are measured.

Lead zirconate titanate films for d33 mode cantilever actuators

Sensors and Actuators A: Physical, 2003
Abstract Piezoelectric Pb(Zr 0.52 Ti 0.48 )O 3 (PZT 52/48) cantilever actuators that operate in the d 33 mode were fabricated using surface micromaching techniques. The cantilevers are composed of a PZT thin film on a low stress silicon nitride (Si x N y ) support buffered by a layer of ZrO 2 .

Study of a piezoelectric accelerometer based on d33 mode

2016 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA), 2016
A piezoelectric accelerometer based on d33 mode was studied in this work. It is comprised of multiple cantilever beams to support a central seismic mass. The piezoelectric PZT thin films and interdigital (IDT) electrodes are designed to be deposited on the surface of beams. The PZT thin film was in-plane polarized and worked in d33 mode.

Acoustoelectric probe for d33 measurement on piezoelectric thin films

Review of Scientific Instruments, 2003
An acoustoelectric probe capable of measuring the d33 constant of piezoelectric thin films is presented. The principle used is the direct piezoelectric effect: a mechanical stress is applied to the film surface and the subsequent voltage generated is measured and compared with a reference.

Poling effect on d33 in textured Bi0.5Na0.5TiO3-based materials

Scripta Materialia, 2013
Textured (1 − x − y)Bi0.5Na0.5TiO3–(x)BaTiO3–(y)K0.5Na0.5NbO3 ceramics have been produced by tape casting with pure-phase Bi0.5Na0.5TiO3 templates. Rietveld texture refinement was used to analyze the crystallographic preferred orientation of the fired ceramics. The effect of poling field on d33 was investigated for applied fields between 0–8 MV m−1 for

d33 mode piezoelectric diaphragm based acoustic transducer with high sensitivity

Sensors and Actuators A: Physical, 2013
Abstract This paper presents the design, fabrication, and characterization of an acoustic transducer using a piezoelectric freestanding bulk diaphragm as the sensing element. The diaphragm bearing the spiral electrode operates in d 33 mode, which allows the in-plane deformation of the diaphragm to be converted to the out-of-plane deformation and ...

Enhanced d33 value in HfO2-modified (Ba0.98Ca0.02)(Ti0.94Sn0.06)O3 ceramics

Journal of Alloys and Compounds, 2013
Abstract In this work, the HfO2 has been used to improve the piezoelectric behavior of (Ba0.98Ca0.02)(Ti0.94Sn0.06)O3 (BCTS) lead-free ceramics prepared by the conventional solid-state method. The addition of HfO2 cannot change the phase structure of BCTS ceramics, showing the formation of an orthorhombic phase.

Giant piezoelectric d33 coefficient in ferroelectric vanadium doped ZnO films

Applied Physics Letters, 2008
A giant electromechanical d33 coefficient 110pC∕N is obtained in ferroelectric V-doped ZnO films, which is nearly one order of magnitude higher than that of undoped samples. It is considered that the switchable spontaneous polarization induced by V dopants and the accompanying relatively high permittivity should be responsible for the enhancement of ...

Design and fabrication of a D33-mode piezoelectric micro-accelerometer

Microsystem Technologies, 2019
In this paper, a D33-mode piezoelectric micro-accelerometer with Pb1.1(Zr0.52Ti0.48)O3(PZT) thin film is designed, fabricated and tested. Both the polarization and deformation directions of the piezoelectric thin film are horizontal in this structure.
