Significance The molecular-scale phenomena that lead to the emergence of the flexoelectric effect in elastomers are not well understood. We present a molecular-to-continuum scale theory and show it to be valid for common types of elastomers. We unravel a mechanism for achieving giant flexoelectricity—which finds support in prior experimental results. The multiscale theory is then leveraged for material design and we propose specific modalities for 1) the emergence of piezoelectricity, 2) tuning…

Group action Markov chain Monte Carlo for accelerated sampling of energy landscapes with discrete symmetries and energy barriers

A new Monte Carlo method, group action Markov chain Monte Carlo (GA-MCMC), which augments more conventional trial moves with the application of a group action from a well-chosen generating set of the discrete symmetry group, and is shown to consistently outperform the considered alternatives, even when the symmetry of the potential energy function is broken.

Flexoelectricity in two-dimensional crystalline and biological membranes.

This review highlights the recent advances made in the understanding of flexoelectricity in two-dimensional membranes-whether the crystalline ones such as dielectric graphene nanoribbons or the soft lipid bilayer membranes that are ubiquitous in biology and focuses on rapidly emerging directions in this field.

Nonlinear bending deformation of soft electrets and prospects for engineering flexoelectricity and transverse (d31) piezoelectricity.

This work analyzes nonlinear bending deformation of a soft electret structure and examines the precise conditions that may lead to a strong emergent piezoelectric response under bending, showing that non-uniformly distributed dipoles and charges in the soft electrets lead to an apparent electromechanical response that may be ambiguously and interchangeably interpreted as either transverse piezOElectricity or flexoelectrics.

It is shown that the presence of another form of electromechanical coupling, flexoelectricity, leads to size effects that dramatically alter the electromech mechanical response at submicron feature sizes.
