WebLead zirconate titanate (PZT) is an inorganic, ceramic, piezoelectric, crystal used in ultrasound transducers. The chemical formula of PZT is Pb[Zr(x), Ti(1-x)]O 3, e.g. PbZr (0..52) Ti (0.48) O 3. Each individual PZT lattice cell has piezoelectric potential due to the dipole created by the asymmetry of the position of its atoms. WebSep 5, 2024 · The PZT-based damage identification methods can be classified into two categories: impedance-based method and vibration-characteristic-based wave propagation (WP) method. The impedance method aims to assess the status of a structure through the mechanic-electric coupling between the piezoelectric material and the host structure.
