A Stress Test for Determination of Certain Piezoelectric Properties of Small Piezoelectric Ceramic Rings

Abstract

Piezoelectricity is defined as pressure electricity. It is a property of polarized PZT (lead-zirconate-titanate) ceramic rings. As the name suggests, electricity is developed when pressure is applied to the rings. The reverse is also true. When an electric field is applied, the ceramic rings deform physically. The ceramic rings used do not have piezoelectric properties in their original state, however, piezoelectric behavior is induced when the rings are poled. The polarized rings are used in transducer stack constructions. A stress test, employing a Carver press, is performed on the piezoelectric ceramic rings in order to determine certain material parameters. The values of voltage, charge and capacitance are examined versus the static stress level on the ceramic rings. The information gathered is used to determine the variations of the material parameters d33, g33 and K33 with stress level.
