Contributions from domain wall motion and properties at the morphotropic phase boundary are considered and are compared to those in PZT. Lead-free, non-piezoelectric solutions to electromechanical coupling are discussed.Lead-freepiezoelectricsferroelectricssodium-bismuth titanatepotassium niobate.text::journal::journal article::research article
