Template-based fluoropolymer ferroelectrets with multiple layers of tubular channels
(2010-12-01)
Significant efforts are devoted to developing new ferroelectrets with well-controlled void distributions or uniform voids and with good long-term and thermal stability of the piezoelectricity. Here, we describe the concept, ...
Influence of PZT insertion on Portland cement curing process and piezoelectric properties of 0–3 cement-based composites by impedance spectroscopy
(2020-03-30)
0–3 Cement-based piezoelectric composites were produced. It was verified that not only the piezoelectric properties of the composites, but also the influence of piezoelectric phase in the cement paste curing process. The ...
Phase transition, dielectric and piezoelectric properties of Li xK1-x NbO3
(Elsevier, 2014-10)
The influence of Li impurities on the phase transition, dielectric and piezoelectric properties of KNbO3 ceramics is investigated. We found that Li doping alters the transition temperatures of KNbO3. While the temperature ...

Electrode poling of cellular polypropylene films with short high-voltage pulses
(2002-01-01)
Recently, piezoelectric cellular polypropylene (PP) was proposed as a new type of quasi-ferroelectric. The observed hysteresis of the charge density as a function of the electric field could be explained as field-dependent ...

Toward Optimal Design of Piezoelectric Transducers Based on Multifunctional and Smoothly Graded Hybrid Material Systems
(SAGE PUBLICATIONS LTD, 2009)
This work explores the design of piezoelectric transducers based on functional material gradation, here named functionally graded piezoelectric transducer (FGPT). Depending on the applications, FGPTs must achieve several ...
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 ...
