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 ...
Modeling of functionally graded piezoelectric ultrasonic transducers
(ELSEVIER SCIENCE BV, 2009)
The application of functionally graded material (FGM) concept to piezoelectric transducers allows the design of composite transducers without interfaces, due to the continuous change of property values. Thus, large ...
PHB/PZT composite
(2005-12-01)
Flexible standing films of piezoelectric composite made of lead zirconate titanate (PZT) ceramic powder and Poly(3-hydroxybutyrate) (PHB) in powder form were obtained by mixing both polymers mechanically and pressed at ...

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, ...

Computational and experimental characterization of a low-cost piezoelectric valveless diaphragm pump
(SAGE PUBLICATIONS LTDLONDON, 2012)
Flow pumps act as important devices in areas such as Bioengineering, Medicine, and Pharmacy, among other areas of Engineering, mainly for delivering liquids or gases at small-scale and precision flow rate quantities. ...
Electromechanical characterization of piezoelectric polymer thin films in a broad frequency range
(Elsevier, 2014-08)
Piezoelectric materials are usually characterized using resonant methods. However, piezoelectric polymers are used in broadband devices, thus requiring characterization over a wide range of frequencies. In this work, we ...
Understanding the piezoelectric properties in potassium-sodium niobate-based lead-free piezoceramics: Interrelationship between intrinsic and extrinsic factors
(Elsevier, 2017-04-26)
Lead zirconate titanate (PZT) based ceramics are currently enjoying a wide use in piezoelectric devices despite lead toxicity. Due to growing environmental concerns, the attention on piezoelectric ceramics has been moving ...
