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 ...

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 ...

Numerical modeling of ferroelectric materials in the presence of flexoelectricity
Higher-order two-way electromechanical coupling between strain gradients and electric field, known as flexoelectricity, has a strong influence on the micro- and nanoelectromechanical devices characterization as it is highly pronounced on smaller scales ...

Flexoelectric Effects of Nanoscale Electrical Materials Under Dynamic Conditions
Energy Science & EngineeringMaterial 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,

A quantitative model of triboelectric charge transfer
FrictionTriboelectricity, 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.
