As the most promising material for high precision displacement actuators, piezoelectric materials have been extensively studied in the past few decades. The strain response characteristics of piezoelectric materials are very important for its applications in actuators. In this paper, three kinds of techniques for improving strain response of piezoelectric ceramics and their research status are briefly reviewed. In addition, we also summarize our ideas on improving the strain response of piezoelectric ceramics combined with the research work.
