Flexoelectricity was investigated as a function of temperature in paraelectric and ferroelectric phases of barium titanate ceramic. The flexoelectric coefficientμ12was measured dynamically at small level of strain gradients.μ12is around5μC∕min orthorhombic phase, rises to about10μC∕mat room temperat...

In this paper, the variation of piezoelectricity of sodium bismuth titanate-barium titanate (NBBT) ceramics after high temperature reduction was researched. A kind of ceramic with piezoelectric and flexoelectric properties was obtained by reducing one surface of ceramics at a high temperature. The ...

The NF-PENGs are composed of poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) nanofibers with embedded barium strontium titanate (BaSrTiO3) nanoparticles, which are fabricated by using facile, scalable, and cost-effective fiber-forming methods, including electrospinning and solution blowing...
Flexoelectricity is a type of ubiquitous and prominent electromechanical coupling, pertaining to the electrical polarization response to mechanical strain gradients that is not restricted by the symmetry of materials. However, large elastic deformation i

Flexoelectricity has been experimentally confirmed in several crystalline materials such as NaCl, ferroelectrics like Barium Titanate among others, e.g. Refs. (Fu et al., 2006, Fu et al., 2007). The mechanisms of flexoelectricity in polymers (while experimentally proven) still remain unclear (...
Piezoelectric effect is observed in myriad naturally occurring materials (quartz, Rochelle salt), biological substances (DNA, viral proteins, bones, enamel), ceramics (Barium titanate (BaTiO3), lead zirconate titanate (PZT)), polymers (Polyvinylidene fluoride) to mention a few. It has been ...
Converse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This situation invariably happens in p
