Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue of Crystals entitled “Piezoelectric Materials and Technology”. Piezoelectric materials constitute various types of crystals, polymers, ceramics, and composites that are used in numerous applications requiring a coupling between electrical fields and mechanical strain. They include actuators, sensors, accelerators, transducers, filters and resonators, energy harvesters, PZT nanorods, and nanowires and nanofibers for MEMS and NEMS devices. 

The main objective of this Special Issue is to collect current research efforts contributing to advances in engineering applications that utilize piezoelectric technologies. The specific topics of interest include, but are not limited to: energy harvesting using piezoelectric materials and devices, sensors and actuators, piezoelectric composite materials, design/fabrication of piezoelectric materials, modeling of piezoelectric materials, piezoelectric nanomaterials, properties of piezoelectric composites, vibration analysis of piezoelectric beams and plates, uses of piezoelectric devices in engineering and medical applications, piezoelectricity in materials, and any other advanced research or application using the piezoelectric phenomenon and/or device.

We look forward to your contributions.

Characterization of Pure Face-Shear Strain in Piezoelectric α-Tellurium Dioxide (α-TeO2)

Paratellurite, also known as α-tellurium dioxide, is a ceramic that is primarily employed for its interesting optical properties. However, this material’s crystal structure belongs to the 422 symmetry class that allows a unique piezoelectric behavior to manifest itself: deformation in pure face-shear. This means that crystal symmetry necessitates the piezoelectric tensor to have only a single non-zero coefficient, d123 = d14: such unique behavior has the potential to enable novel gyroscopic sensors and high-precision torsional microelectromechanical systems (MEMS) actuators, as pure face-shear can be used to induce pure torsion. Although α-TeO2 is one of the few known materials belonging to this symmetry class, considerable uncertainty in its single piezoelectric coefficient exists, with the few reported literature values ranging from 6.13 to 14.58 pC/N; this large uncertainty results from the difficulty in using conventional piezoelectric characterization techniques on paratellurite, limiting measurements to indirect methods. The novel applications that would be enabled by the adoption of this extraordinary material are frustrated by this lack of confidence in the literature. We therefore leverage, for the first time, a first-principles analytical physical model with electrochemical impedance spectroscopy (EIS) to determine, directly, the lone piezoelectric coefficient d123 = d14 = 7.92 pC/N.
