Special Issue Information

Dear Colleagues,

Ferroelectric materials have wide promising applications in computer RAM, sensing, imaging, chemical reaction catalyses, precision driving motors, micro/nano/molecular manipulations, energy harvesting, transduction, etc. This Special Issue covers the latest advances in ferroelectric materials, piezoelectric actuators, and their applications. Thematic areas include (i) the relationships between the processing, structure, microstructure, and functional response of ferroelectric and related materials in the form of bulk polycrystalline ceramics, single crystals, and thick or thin films, (ii) novel functionalities or a combination of properties oriented toward new application areas, and (iii) the modeling and characterization of piezoelectric materials and their performance in a wide range of devices and applications. The topics in this Special Issue include, but are not limited to:

  • Advances in ferroelectric materials;
  • Multiferroic materials and devices;
  • Ferroelectric capacitors, RAM, and tunnel junctions;
  • Pyroelectric and electrocaloric (multicaloric) devices;
  • Adsorption and catalytic properties of ferroelectrics;
  • Piezoelectric energy harvesting;
  • Piezoelectric/ultrasonic motors;

The objective of this work is to characterize the nonlinear dependence of the piezoelectric d15 shear coefficient of a composite actuator on the static electric field and include this effect in finite element (FE) simulations. The Levenberg-Marquardt nonlinear least squares optimization algorithm implemented in MATLAB was applied to acquire the piezoelectric shear coefficient parameters. The nonlinear piezoelectric d15 shear constant of the composite actuator integrated with piezoceramic d15 patches was obtained to be 732 pC/N at 198 V. The experimental benchmark was simulated using a three-dimensional piezoelectric FE model by taking piezoelectric nonlinearity into consideration. The results revealed that the piezoelectric shear d15 coefficient increased nonlinearly under static applied electric fields over 0.5 kV/cm. A comparison between the generated transverse deflections of the linear and nonlinear FE models was also performed. Full article
