The ultrahigh-frequency (UHF) ultrasonic transducers are active in various fields, including
nondestructive evaluation in the semiconductor industry, microscopic biological organization …

We investigated the innovative processing of poly (vinylidene fluoride-trifluoroethylene) P
(VDF x-TrFE 1-x)(x= 83 mol.%) by inkjet printing to deliver uniform and thickness-controlled …

Porous ceramics are of interest for ultrasonic transducer applications. Porosity allows to
decrease acoustical impedance, thus improving transfer of acoustical energy to water or …

The use of porosity to modify the functional properties of piezoelectric ceramics is well
known in the scientific literature as well as by the industry, and porous ceramic can be seen …

We studied the effect of porosity and pore morphology on the functional properties of Pb
(Zr0. 53Ti0. 47) O3 (PZT) ceramics for application in high frequency ultrasound transducers …

For transducer design, it is essential to know the acoustic properties of the materials in their
operating conditions. At frequencies over 15 MHz, standard methods are not well adapted …

In this study, high performance piezoelectric thick films were prepared by depositing only a
few sol–gel infiltrated composite layers on Si/SiO2/Ti/Pt wafers. Lead zirconate titanate (PZT) …

Piezoelectrics are key materials for energy conversion, for example in ultrasound
transducers and energy harvesters. This work presents the synthesis and characterization of …

Abstract Lead–zirconate–titanate PbZr (1− x) Ti x O 3 (PZT), materials for piezoelectric
applications are the dominant piezoceramics since their properties are high. However PZTs …
