PZT is one of the most common piezoelectric materials, in the name of which its composition is encoded: Pb - Zr - Ti or lead zirconate-titanate. The material has gained its popularity due to its pronounced piezoelectric properties, which are complemented by the simplicity of its production, and, as a result, its relatively low cost, as well as its ease of use for end use.
