Morphotropic phase boundary (MPB), a highly sought-after concept in piezoelectric materials, is the key factor for large electromechanical response. Unfortunately, mainstream piezoelectric materials all contain lead, a toxic element that is incompatible to the ever-growing demands for global environ...
