Actuator Systems Based On Piezoelectric Ceramics

Piezoelectric actuators are a new field of research combining electronic and structural ceramics. Abstract new sensors and actuators based on emerging transducer technologies can play a crucial role in the field of biomedical instrumentation and rehabilitation technologies. Although pure batio3 material exhibits fairly low piezoelectric coefficients further designing of such a material system greatly enhances the piezoelectric response by means of domain engineering defects engineering as well as phase boundary engineering.
