Abstract Scope The bandwidth capability of acoustic devices is dependent on the electromechanical coupling (kij) of the active piezoelectric elements. Textured ceramics have emerged as a promising solution to meet high-bandwidth needs by demonstrating large coupling factors greater than 0.80 which approach those of ultra-high coupling single crystals (k33 > 0.90). This work discusses key factors of electromechanical coupling and relationships with microstructure, chemistry, and crystallographic alignment. A well-studied model system of Pb(Mg1/3Nb2/3)O3-PbTiO3 (i.e. PMN-PT) is selected and the effects of platelet-shaped seed particles (BaTiO3) within the microstructure are explored. The effects of varying seed size and distribution on the resulting grain size and electromechanical response in terms of piezoelectric coefficients dij and kij are discussed. Finally, new material chemistries are explored that maximize electromechanical coupling coefficients to >0.85, unveiling the roadmap to development of novel compositionally and microstructurally tuned high-bandwidth piezoelectric materials.
