Multi-Layer Textured Piezoelectric Ceramics

Effective multilayer devices (for example, multilayer actuators) require materials with high electromechanical properties. By combining the TGG method with low-temperature cofiring ceramics (LTCC) techniques, we successfully co-fired textured piezoelectric ceramics materials that have silver inner electrodes and high electromechanical properties. Using silver alleviates the need for using Pt/Pd. These multilayer textured piezoelectric ceramics have significantly enhanced electromechanical performance when compared to non-textured ceramics. This material seems promising for use in applications including actuators, ultrasonic transducers, and energy harvesters.
