Effect of Flexoelectricity on the Electromechanical Coupling of Piezoelectric Nanoplates
Bibliographic record
Abstract
Flexoelectricity is referred as an instantaneous polarization of dielectrics in response to non-uniform strains or strain gradients.Due to the fact that strain gradients are inversely proportional to the feature size of structures, the flexoelectricity is believed to be significant at the nano-scale.Based on the extended linear piezoelectricity theory, this work attempts to investigate the flexoelectric effect upon the electromechanical coupling of a piezoelectric nanoplate by developing a modified Kirchhoff plate model.Simulation results on the electroelastic fields indicate that the flexoelectric effect is size-dependent, which is more prominent for thinner plates with smaller thickness.It is also observed that the effect of the flexoelectricity upon the electromechanical coupling of the piezoelectric nanoplate is sensitive to the applied electric voltage.This study aims to establish a further understanding of the flexoelectric effect on the electromechanical coupling of piezoelectric nanomaterials, thus provide guidance for the design and applications of piezoelectric nanostructures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
