Abstract

A promising pathway to maximize the performance of lead-free piezocomposites involves optimizing complex coupled processes such as flexoelectricity, geometric structure of the piezocomposite material and device, and the choice of materials. Here, we present a simple example demonstrating how the performance of pieozocomposites can be boosted significantly using a combination of geometric anisotropy and optimal mechanical properties of the matrix material. The optimal design is conducive to large strain gradients that lead to considerable flexoelectric enhancement to the electromechanically coupled response of the composite to applied mechanical stimuli.
