Near-ideal electromechanical coupling in textured piezoelectric ceramics
Abstract
“k” is the electromechanical coupling factor, and determines the efficiency of conversion between electrical and mechanical energy or vice-versa in piezoelectric materials. Here, Yan et al. present an optimization strategy for “k” via texturing and covalency tuning that results in “k” values comparable to that of single crystals.
