Piezoelectric Accelerator [PDF]

Scientific Reports, 2018
AbstractHere we propose the conception of small-size piezoelectric accelerator of charged particles that operates due to the piezoelectric effect at varying mechanical force applied to piezoelectrics in vacuum. The accelerating voltage and the energy of accelerated particles are estimated.

Measurement of Flexoelectric Effect in Lead Zirconate Titanate Ceramics

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011
Lead zirconate titanate (PZT) ceramics is usually used as a piezoelectric material. However it has characteristics of not only piezoelectricity but also flexoelectricity.

Piezoelectric mimicry of flexoelectricity [PDF]

, 2018
The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectric-like effects with parasitic piezoelectricity ...

Piezoelectricity in nominally centrosymmetric phases

Physical Review Research, 2021
Compound phases often display properties that are symmetry forbidden relative to their nominal, average crystallographic symmetry, even if extrinsic reasons (defects, strain, or imperfections) are not apparent.

High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system [PDF]

, 2012
In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedicated to the classical piezoelectric, lead-zirconate-titanate (PZT) ceramic ...
