Constructive and destructive interplay between piezoelectricity and flexoelectricity in flexural sensors and actuators [PDF]

, 2020
Flexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its size-dependence and symmetry.

Flexoelectric Effects of Nanoscale Electrical Materials Under Dynamic Conditions

Energy Science & Engineering
Material flexoelectricity is due to strain gradients at the material's small dimensions, and nanoelectronics more precisely enhances the heightened sensitivity at this reduced scale. Below, the study presents a sensitivity analysis in active applications,

Piezoelectric mimicry of flexoelectricity

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 flexoelectriclike effects with parasitic piezoelectricity ...

Molecular theory of flexoelectricity in nematic liquid crystals

, 2013
The molecular-statistical theory of flexoelectricity in nematic liquid crystals is considered in detail and general expressions for the flexoelectric coefficients are obtained in terms of the direct correlation function.

Enabling nanoscale flexoelectricity at extreme temperature by tuning cation diffusion

, 2018
Any dielectric material under a strain gradient presents flexoelectricity. Here, we synthesized 0.75 sodium bismuth titanate −0.25 strontium titanate (NBT-25ST) core–shell nanoparticles via a solid-state chemical reaction directly inside a transmission ...

Flexoelectric Polarization‐Enhanced Gd‐Based Nanoflowers for Efficient Phosphatase‐Mimicking Dephosphorylation

Small Structures
Phosphatase‐mimicking nanozymes provide highly stable enzyme‐like activity but remain limited by their static catalytic nature. Herein, this study achieves flexoelectricity‐driven dynamic modulation of nanozyme activity by employing gadolinium‐based ...

Flexoelectricity and surface ferroelectricity of water ice

Frozen water at ambient pressure—common ice, also known as hexagonal Ih ice—is a non-polar material, even though individual water molecules are polar. Consequently, ice is not piezoelectric and cannot generate electricity under pressure.
