Conservation Integrals in Nonhomogeneous Materials with Flexoelectricity

open access: yesApplied Sciences, 2021
The flexoelectricity, which is a new electromechanical coupling phenomenon between strain gradients and electric polarization, has a great influence on the fracture analysis of flexoelectric solids due to the large gradients near the cracks. On the other

Verification of the flexoelectricity in barium strontium titanate through d33 meter

open access: yesAIP Advances, 2016
Flexoelectricity is a newly arising electromechanical property that couples strain gradient to polarization. This physical property widely exists in most of the solid dielectrics but has quite weak response that often overlooked.

Effect of Pre-Polarization Process on the Apparent Piezoelectric Response Measured by Point-Ring Method in Ferroelectric Perovskite Oxide Ceramics

open access: yesEnergies, 2022
Both flexoelectricity and piezoelectricity belong to the electromechanical coupling effect. While piezoelectricity only exists in materials whose crystal structure is noncentrosymmetric and a pre-polarization process is necessary for ferroelectric ...

Flexoelectricity in thin films and membranes of complex oxides

open access: yesAPL Materials, 2020
Flexoelectricity describes the generation of electric polarization in response to inhomogeneous strain, i.e., strain gradient, in all dielectrics. Importantly, strain gradients are inversely scaled to the material dimension so that more prominent and ...
