1-3 castor oil-based polyurethane/PZT piezoelectric composite as a possible candidate for structural health monitoring
(2020-10-26)
In this study, we obtained and characterized a piezoelectric composite with 1-3 connectivity from castor oil polyurethane (PUR) and lead zirconate titanate (PZT) rods. Two samples were obtained, one with 15% PZT volume and ...
Influence of B-site compositional homogeneity on properties of (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3-based piezoelectric ceramics
(Elsevier, 2014-03-05)
The effect of B-site compositional homogeneity on microstructure, piezoelectric properties and dielectric behaviour of lead-free piezoelectric ceramics, (K0.44Na0.52Li0.04) (Nb0.86Ta0.10Sb0.04)O3, is investigated. The ...
Electroactive properties of flexible piezoelectric composites
(ABM, ABC, ABPol, 2001-07)
A flexible piezoelectric composite with 0-3 connectivity, made from Lead Zirconate Titanate (PZT) powder and vegetable-based polyurethane (PU), was doped with small amount of semiconductor powder. As a result a composite ...
Bayesian identification of electromechanical properties in piezoelectric energy harvesters
(Elsevier, 2020)
The model updating of the electro-mechanical properties of Piezoelectric Energy
Harvesters (PEHs) using experimental data within a Bayesian inference setting is discussed.
The implementation requires: a predictive model ...
Influence of zirconium addition on final properties of K0.5Na0.5NbO3-based ceramics
(Springer, 2013-11-08)
Microstructure, electrical and dielectric properties of K1/2Na1/2NbO3 (KNN) modified with ZrO2 were investigated. Powders were obtained by a conventional solid-state method. In this way, samples doped with 0.2 mol% of ZrO2 ...
Microscopic scale investigation of piezoelectric properties of lead-free alkaline niobates
(American Institute of Physics, 2013-12-09)
A first-principles-based technique is used to investigate the electromechanical properties oflead-free alkaline niobates. In particular, we study the structural and piezoelectric properties of LixK1-x NbO3 which is taken ...
Morphotropic phase boundary and electrical properties of 1-x[Bi 0.5Na0.5]TiO3 -xBa[Zr0.25Ti 0.75]O3 lead-free piezoelectric ceramics
(2013-07-01)
Lead-free solid solutions (1-x)Bi0.5Na0.5TiO 3 (BNT)-xBaZr0.25Ti0.75O3 (BZT) (x=0, 0.01, 0.03, 0.05, and 0.07) were prepared by the solid state reaction method. X-ray diffraction (XRD) and Rietveld refinement analyses of ...
