Paper Abstract

A plate of PZT5h was prepared with a single electrode on one face connected to a power amplifier. The opposite face was left as bare ceramic material which was then exposed to an electron beam. Sixteen strain gages were attached atop the electrode to measure the strain response and as a function of electrode potential (backpressure voltage). A range of sinusoidal voltage inputs were applied to the electrode and the strain response and current draw through the PZT were recorded. Electrode potentials between -15 and 100 V yield very predictable strain response and extremely small currents (approcimately 10-7 - 10-6 microamperes) which appear to be independent of the electrode potential. Below -15 V the current through the PZT suddenly increases to 10 (mu) a. At -15 volts level the strain response is still predictable but, as the electrode voltage decreases the strain signal begins to display significant drift. The root cause of this phenomenon is examined with the aid of the deBroglie-Einstein postulate and the Schr*dinger wave equation.
