## What is/are Piezoelectric Nanobeams?

Piezoelectric Nanobeams - The static and dynamic responses of piezoelectric nanobeams which taking the flexoelectric effect into account are studied.^{[1]}Presented herein is a size-dependent Bernoulli–Euler beam model for the buckling analysis of piezoelectric nanobeams under electrical loading with the consideration of flexoelectricity influence.

^{[2]}Numerical results are presented to study the influences of nonlocal, flexoelectric and Winkler/Pasternak parameters on the bending response of piezoelectric nanobeams under various end conditions.

^{[3]}In the present paper, we analyze the influence of surface effect on the nonlinear bending behavior of piezoelectric nanobeams by Euler-Bernoulli model and surface energy model.

^{[4]}In addition, changes in the external applied voltage have a significant effect on the natural frequency of the piezoelectric nanobeams and increasing the thickness of the piezoelectric layer can enhance the structural stiffness.

^{[5]}The vibration analysis of piezoelectric nanobeams under thermal-mechanical-electrical multiple physical fields is performed that aims to be a self-powered component of medical nanorobots.

^{[6]}Based on a paradox-free nonlocal theory—two-phase local/nonlocal elasticity—vibration, buckling, and energy harvesting of piezoelectric nanobeams are investigated for the first time.

^{[7]}ABSTRACT This manuscript illustrates coupled effects of nonlocal elasticity and surface properties on static and vibration characteristics of piezoelectric nanobeams using thin beam theory.
