Dramatic amplification of the flexoelectric effect in snapping surfaces
Journal of applied mechanics, 2023Flexoelectricity exists in all inhomogeneously deformed dielectric materials and is greatly interesting in engineering science, especially in manufacturing microelectromechanical systems.

Asymmetric fracture behavior in ferroelectric materials induced by flexoelectric effect
Journal of Applied Physics, 2023Ferroelectric materials are widely used in actuators, exciters, and memory devices due to their excellent electromechanical properties. However, the instinctive brittleness of ferroelectric materials makes them easy to fracture under external load. Since

Flexoelectric effect in elastomers
2007Electric polarization induced by a nonhomogeneous deformation field — flexoelectricity — has been investigated in elastomers. A simple model of dipole orientation mechanism controlled by anisotropic free volume is given. The order of magnitude of the polarization to the deformation gradient ratio β predicted by the model is β ∼ 10−11 C/m.

Waves in Random and Complex Media, 2022
The present research article aims to describe that the flexoelectric affects the propagation of Love-type in various piezoelectric (PE) materials bars (PZT-7A, PZT-5A, PZT-6B, PZT-4, PZT-2) that rest over a silicon oxide plate under the presence of a ...

FLEXOELECTRIC EFFECT IN FERROELECTRICS
Functional Materials Letters, 2008Flexoelectric effect and its influence on the application of multifunctional ferroelectrics have been investigated. Theory of flexoelectric coupling has indicated that mechanical strain gradient can impact polarization in a way analogous to electric field. Experimentally, magnitudes of the flexoelectric coefficients have been measured in ferroelectric,

Mathematical Modeling of Flexoelectric Effect
2018To study the flexoelectric effect, a three-point excitation model for a piezoelectric element with a proof mass at its center was selected. This type of excitation occupies an “intermediate” place between cantilever- and stack-type PEGs. The axial action of the proof mass along the center of the plate leads to an elastic deflection (see Fig.

Piezoelectric and flexoelectric effects in ferroelectric liquid crystals
Physical Review E, 2012Flexoelectric and piezoelectric effects in ferroelectric liquid crystals (FLCs) have been studied. It is shown that nonlinear electromechanical coupling is determined by a local flexoelectric effect. Dependence of the parameters of nonlinearity of the flexoelectric effect on the parameter of phase transition from a paraelectric phase to a polar phase ...
