Effect of normal vibration on the dynamic flexoelectric response of a thin dielectric plate with symmetrical electrode thickness

open access: yesAlexandria Engineering Journal
In this paper, we investigate the effect of thickness-normal vibration on the dynamical flexoelectric effect induced in a thin dielectric plate covered by two electrodes with either equal or unequal thicknesses.

Effect of annealing on flexoelectricity in hafnium oxide (HfO2)

open access: yesApplied Physics Letters
Flexoelectricity is universal in all dielectrics, effective at high temperatures, and a promising transduction technique for nanoelectromechanical systems (NEMS). However, as flexoelectricity is still in its early stages, many aspects require further investigation.

On the coupling effects of piezoelectricity and flexoelectricity in piezoelectric nanostructures

open access: yesAIP Advances, 2017
Flexoelectricity is a novel kind of electromechanical coupling phenomenon that is prevalent in all solid dielectrics and usually of vital importance in nanostructures and soft materials. Although the fundamental theory of flexoelectric solids and related

Bending stress analysis of a piezoelectric nanoplate with flexoelectricity under inhomogeneous electric fields

open access: yesAIP Advances, 2019
Flexoelectricity has been found as an unneglectable electro-mechanical coupling effect in micro/nanoscale dielectric materials. We present a stress function based bending stress analysis method for piezoelectric nanoplate under inhomogeneous electric ...

Topological transition from a hopfion to a toron via flexoelectric self-polarization in chiral liquid crystals

open access: yesPhysical Review Research
The presence of topological defects in apolar chiral liquid crystals causes orientational distortions, leading to nonuniform strain. This nonuniform strain generates an electric polarization response due to the flexoelectric effect, which induces an ...
