Fundamentals of flexoelectricity in solids [PDF]
Nanotechnology, 2013 The flexoelectric effect is the response of electric polarization to a mechanical strain gradient. It can be viewed as a higher-order effect with respect to piezoelectricity, which is the response of polarization to strain itself. However, at the nanoscale, where large strain gradients are expected, the flexoelectric effect becomes appreciable. Besides,

Verification of the flexoelectricity in barium strontium titanate through d33 meter
AIP 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.

Applications of Flexoelectricity
, 2012 There have been a number of attempts to utilize the flexoelectric effect for electro-optic devices. Most of these have been aimed at new display modes, sometimes inspired by the twisted nematic (TN) cell and often with the aim of attaining bistability ...

Enhanced flexoelectricity at reduced dimensions revealed by mechanically tunable quantum tunnelling [PDF]
Nature Communications, 2019 Flexoelectricity exists in every dielectric material exposed to a strain gradient and is enhanced at the nanoscale. However, precisely determining flexoelectric coupling parameters at the nanoscale is challenging, but has been overcome here by measuring ...

Flexoelectric Blue Phases [PDF]
Physical Review Letters, 2007 We describe the occurence and properties of liquid crystal phases showing two dimensional splay and bend distortions which are stabilised by flexoelectric interactions. These phases are characterised by regions of locally double splayed order separated by topological defects and are thus highly analogous to the blue phases of cholesteric liquid ...

Energies, 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 ...
