Flexoelectricity in ferroelectric materials
IET Nanodielectrics, 2019 Flexoelectricity is a gradient electromechanical effect that exists in all solid dielectrics. The effect was first predicted in the late 1950s, but received little interest because it was expected to be small.

Electromechanical Analysis of Flexoelectric Nanosensors Based on Nonlocal Elasticity Theory
Micromachines, 2020 Flexoelectric materials have played an increasingly vital role in nanoscale sensors, actuators, and energy harvesters due to their scaling effects. In this paper, the nonlocal effects on flexoelectric nanosensors are considered in order to investigate ...

Flexoelectricity in antiferroelectrics [PDF]
Applied Physics Letters, 2018 Flexoelectricity (coupling between polarization and strain gradients) is a property of all dielectric materials that has been theoretically known for decades, but only relatively recently it has begun to attract experimental attention. As a consequence, there are still entire families of materials whose flexoelectric performance is unknown. Such is the

Flexoelectric effect modelling [PDF]
Opto-Electronics Review, 2008 AbstractA statistical theory of dipole flexoelectric (FE) polarization in liquid crystals is used to calculate temperature dependence of order parameters, elastic constants and FE coefficients. Two systems with polar wedge-shaped and banana-shaped molecules are investigated.

Influence of impact velocity on flexoelectric effect
Results in Physics, 2019 Flexoelectric effect is the coupling of the inhomogeneous deformation and electric polarization, which exists widely in dielectrics. At present, although some scholars have carried out the experimental research on the measurement of the flexoelectric ...

Flexoelectric Effect in Solids
Annual Review of Materials Research, 2013 Flexoelectricity—the coupling between polarization and strain gradients—is a universal effect allowed by symmetry in all materials. Following its discovery several decades ago, studies of flexoelectricity in solids have been scarce due to the seemingly small magnitude of this effect in bulk samples.

Flexoelectricity in soft elastomers and the molecular mechanisms underpinning the design and emergence of giant flexoelectricity [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance The molecular-scale phenomena that lead to the emergence of the flexoelectric effect in elastomers are not well understood. We present a molecular-to-continuum scale theory and show it to be valid for common types of elastomers.
