Field induced acoustic emissions (AE) in damaged ferroelectric ceramics have been studied. The field induced AE was not observed after the poling was completed at given electric fields. However, new AE was generated when the samples were damaged. It has been demonstrated that the AE method can be used to detect the damage of piezoelectric/ferroelectric materials and to determine safe driving electric fields.
