Piezoelectric ceramics are among the most commonly used piezoelectric materials today due to their unique dielectric and piezoelectric properties, their almost unlimited shaping possibilities and their stable chemical composition. The most important piezoceramic materials today are based on the oxide solid solution system PZT, which we have already examined in detail in the previous chapter. The following explanations provide a compact overview of the preparation and manufacturing processes of a PZT ceramic. An overview of the standard designs of piezoelectric actuators found in technical applications, in particular piezoceramic bending transducers, concludes the chapter.
