The PZT System

International audienceCurrently, lead-based compounds such as lead zirconate titanate (PZT) constitute the best family of piezoelectric and ferroelectric materials suitable for integration into devices such as piezoelectric actuators, sensors and transducer. These compounds present excellent piezoelectric and ferroelectric properties and are widely industrially developed. This article describes the structure of PZTs, the piezoelectric phenomenon as well as the different doping techniques. Indeed, the main advantage of this material lies in the great modularity of its properties by the simple modification of its composition
