Abstract

Lead zirconate titanate ceramic actuators are
extensively used in electronic and electro-mechanical devices.
Under humid conditions with a d.c. bias leakage currents
increase power consumption In some materials the increasing
leakage current is accompanied by the evolution of features
on the anode surface, but little is known of any changes to the
internal structure of the material. This research applies an
advanced imaging technique (micro-computer tomography)
to non-destructively investigate these features. This allows
the evolution of internal features over time to be studied. The
findings reveal that the microstructure of the ceramic was
significantly altered during environmental testing.
