Flexoelectricity and Mechanotransduction

2007
Publisher Summary The process of mechanotransduction in membranes benefits from specialized and localized elements such as stress‐activated channels, and also from the collective properties of the mechanosensitive membranes as a whole. These collective properties evolve from the liquid crystal character of membranes and are best understood in terms ...

Flexoelectricity in the Hybrid Aligned Nematic Cell

Molecular Crystals and Liquid Crystals, 1987
The reorientation process of an HAN cell submitted to electric fields is studied both theoretically and experimentally. To isolate the flexoelectric effect from the dielectric one, the experiments are made under d.c. and a.c. excitations. Preliminary results on 6 μm thick MBBA have been reported.

Dispersion and Attenuation Relations in Flexoelectricity

Journal of the Mechanics and Physics of Solids
The dispersion relations in flexoelectricity are examined for plane time-harmonic waves that propagate in the flexoelectric materials. In contrast to classic elastodynamics, dispersion is observed in the displacement field due to two micro-structural and two micro-inertial lengths that emerge from the electromechanical coupling.

Measuring inverse flexoelectric effect at the macro scale and flexoelectric actuator

Journal of Physics D: Applied Physics
Abstract The flexoelectric effect is a two-way mechanical-electrical coupling. The dielectric is polarized when subjected to bending moments, and inversely, the electric field can also induce strain gradients within the dielectric. Although equally important, research on the inverse flexoelectric effect has lagged far behind that on the ...

Streaming flexoelectricity in saline ice

Nature Materials
Despite 10% of the Earth's surface being covered by ice, ice power remains untapped. Although ice is known to generate electricity upon bending via flexoelectricity1, the generated electric polarization per curvature, that is, the flexoelectric coefficient, is too small (~1-10 nC m-1) to be utilized for electromechanical devices.

FLEXOELECTRIC EFFECT IN FERROELECTRICS

Functional Materials Letters, 2008
Flexoelectric 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,
