Flexoelectric Effect in Biaxial Nematics

Acta Physica Polonica A, 2012
The flexoelectric (FE) effect provides a linear coupling between electric polarization and orientational deformation in liquid crystals. It influences many electrooptical phenomena and it is used in some bistable nematic devices. A statistical theory of dipole FE polarization in biaxial nematic liquid crystals is used to calculate temperature ...

A quantitative model of triboelectric charge transfer

Friction
Triboelectricity, when rubbing or contacting materials causes electric charge transfer, is ubiquitous across many fields, and has been studied in detail for centuries. Despite this, a complete description of triboelectricity remains elusive.

Flexoelectric metamaterials optimization

, 2021
Electromechanical couplings play an important role in our day to day lives, as they are present in both natural biological systems and technological applications. Piezoelectricity, the two way coupling between strain and polarization, is one of the most well-known and used mechanism behind electromechanical transduction.

Influence of Flexoelectric Coupling and Interfacial Imperfection on Shear Horizontal Wave Propagation in a Piezoflexoelectric Layer over an Elastic Substrate

Mathematics
This study analytically investigates shear horizontal (SH) wave propagation in a layered structure consisting of a piezoflexoelectric (PFE) layer bonded to an elastic substrate, considering an imperfect interface.

Causal inference in statistics insights into stress-induced ferroelectric states in SrTiO: disentangling piezoelectric and flexoelectric effects from birefringence images

Science and Technology of Advanced Materials: Methods
In materials science, experimental conditions are precisely controlled to ensure high reproducibility. This property is well suited for causal inference in statistics, yet its potential remains unrealized.
