Piezoceramics are used to convert mechanical energy into electrical energy and vice versa. Due to their ability to be tailored towards the requirements of particular applications, they have replaced natural and synthetic piezo crystals in many devices and their application range is continuously expanding. The aim of this work is to provide a clear and useful introduction to piezoceramics that will orient the reader to the selection of the most suitable material for a specific application. After a brief description of the piezoelectric material development, the properties of piezoceramics will be described and correlated with the crystalline structure. Finally, as a case study the various developmental phases of an ultrasonic probe suitable for the dynamic mechanical analysis of polymers at high frequency will be presented
