of critical components and infrastructure across industries. For example, aircraft engines, natural gas pipelines,_x000D_
refinery columns, water lines, and turbine blades are all regularly inspected using ultrasound. Ultrasound is_x000D_
non-destructive, and can therefore be used without damaging the system it is monitoring. This technique helps_x000D_
diagnose fractures, wear, corrosion, and other degradation that, if not caught early, may lead to catastrophic_x000D_
failure. A major limitation of current ultrasound transducers is that they are unable to operate at elevated_x000D_
temperatures (above about 200Â°C) - thereby precluding a wide range of applications, including in-service_x000D_
structural health monitoring (SHM) at high temperatures. One of the primary challenges of operating an_x000D_
ultrasound transducer at high temperature is the deterioration of the active piezoelectric component at_x000D_
temperatures above about 200Â°C. We therefore are investigating the use of a alternative active piezoelectric_x000D_
components that are able to withstand higher temperatures. The research outcome could ultimately lead to the_x000D_
development of a novel ultrasound transducer that is able to withstand high temperatures - thereby enabling_x000D_
