Electroceramics
A piezoelectric material has the ability to change shape when subjected to an electric charge. Conversely, a piezoelectric material is able to generate a charge when it is deformed. Piezoelectric materials are used in applications such as industrial equipment (flow meter, non-destructive testing), automotive (parking sensor, diesel injector), medical (ultrasonography, surgical tool), consumer goods (ink jet printing heads, hard drive) and military (sonobuoy, guidance system). The most commonly used piezoelectric material is Lead Zirconate Titanate (PZT), because the customization of PZT chemical composition allows a wide range of properties. Also, PZT parts can be precisely machined and operate at high temperature
