Lead zirconate titanate (PZT) as a piezoelectric ceramic has been used widely in the fields of electronics, biomedical engineering, mechatronics and thermoelectric. Although, the electrical properties of PZT ceramics is a major considerable, but the mechanical properties such as fracture strength and toughness should be improved for many applications. In this study, lead monoxide, zirconium ...

This study presents the analytical model and 3D simulation of piezoelectric square diaphragm pressure based on PZT-5H PZT-5A. The sensor's stress electrostatic are explained in sensor, all variables impacting induced output voltage covered. Piezoelectric materials such as PZT-5A, PZT-5J, PVDF, PMN-PT, LiNbO3, AlN, ZnO used to create sensors. COMSOL Multiphysics simulator simulates suggested sen...

Single crystalline PbZr(0.2)Ti(0.8) (PZT) nanowires arrays (NWAs) with taper morphology were epitaxially grown on SrTiO(3) (STO) substrate using pulse laser deposition. The taper morphology was attributed to the overcoating of PZT layer via a lateral growth of PZT clusters/adatoms during PZT NW growth. The growth window for PZT film or nanowire was systematically studied at varied temperatures ...

In this work, after investigating three typical magneto-electric (ME) composites, Permendur/Pb(Zr0.52Ti0.48)O3(PZT), Metglas/PZT, and Tefenol-D/PZT, with the same dimensions and different saturation magnetostriction and magnetic permeability, the most excellent ME performance is observed in the Permendur/PZT laminates, which agrees well with the predicted results from the figure of merit. The l...

A multilayer ceramic actuator composed of piezoelectrically active Pb(Zn1/3Nb2/3)0.2–Pb(Zr0.5Ti0.5)O0.8 (PZN–PZT) layers and electrically conducting PZN–PZT/Ag layers was fabricated by the co-extrusion process. For the piezoelectric layers, PZN–PZT, which is sinterable at a low temperature (9001C), was used. For the conducting layers, a PZN–PZT/Ag composite, made by mixing silver particles with...

In this article, we studied how surfactants can impact Pb (Zr0.53Ti0.47) O3 (PZT) nanocrystal formation to result in interesting nanohexagon and nanorod shapes of PZT crystal. The PZT nanohexagons/nanorods with typical diameters and bounding lengths within the nanometer range were synthesized by sintering the mixture of PZT crystals. After annealing at 800 1C for 3 h, PZT nanohexagons were form...

We analyze, numerically by the finite element method, three-dimensional electromechanical deformations of a thick laminated plate with layers made of aluminum, a viscoelastic material and a piezoceramic (PZT). Two arrangements of layers are considered. In one case a central PZT layer is surrounded on both sides by viscoelastic layers and aluminum layers are on the outside surfaces. The PZT is p...

We present a topology optimization framework to design periodic composites comprised of piezoelectric constituents that exhibit large flexoelectric constants. The novelty the approach is it leverages representative volume element (RVE)-based computational homogenization enables analysis where characteristic dimensions microstructure are significantly smaller than those structure, and as such re...

In the last decade, lead zirconate titanate oxide (PZT) thin-film actuators have received increasing attention because of their high frequency bandwidth, large actuation strength, fast response, and small size. The PZT film thickness is usually less than several microns as opposed to hundreds of microns for bulk PZT patches that are commercially available. As a result, PZT thin-film actuators p...
