Ferroelectric Heterostructures Materials Development, Modeling & Testing

Abstract

A materials development effort has been conducted to explore the feasibility of constructing ferroelastic-ferroelectric heterostructures that could be used to dampen shock waves. The original concept proposed to use a thin film of PZT on the front surface to act as a sensor to detect the pressure pulse. TiNi, in both thin-film form and as a porous metal, would be incorporated into the structure to passively damp the stress wave. Finally, another layer of PZT would be introduced to actively damp the pulse by applying a counter pulse. This program investigated aspects of the materials synthesis and interface engineering needed to integrate TiNi and PZT into a single device.
