Piezoelectric sensors and actuators are a mature technology, commonplace amongst a plethora of industrial fields including automotive, maritime and non-destructive testing. However the environments that these devices are required to serve in are becoming more demanding, with temperatures being driven higher to increase efficiencies and reduce shut-downs. Materials to survive these temperatures have been the focus of many research groups over the last decade, but there still remains no standard for the measurement of piezoelectric materials at high temperature. This is required to effectively determine comparable Figures of Merit into which devices can be successfully designed. As part of a recent European effort to establish metrological techniques for high temperature evaluation of electro-mechanical properties, we present here a review of the most promising high temperature polycrystalline materials. Where their properties allow operation above that of the ubiquitous commercial material lead zirconate titanate, as well as work done to modify a promising high temperature system, for use as a material standard. © 2015 The Author(s)

Piezoelectric materials are used to produce and sense ultrasound in instrumentation used to monitor structural integrity, monitor flows and measure distance variations in a rnage of industrial environments. Ionix Advanced Technologies specializes in piezoelectric materials and ultrasound devices for the high temperature applications in this field. The project will develop a new form of piezoelectric material, a composite comprising a piezoelectric ceramic and a porous glass which will exhibit advantageous properties for ultrasound use at high temperatures. The resulting instruments will have high sensitivity, improved spatial resolution and much improved signal to noise ratio, enabling new applications for these systems in safety critical applications in power generation, the oil & gas industry, plus the automotive and aerospace sectors.

This project will test whether a new piezoelectric material, for use in structural health monitoring systems, is suitable for use in nuclear power generation plants. The materials resistance to to radiation damage will be assessed by testing the functional properties of the material after exposure to various doses of radiation. If the radiation hardness is sufficient, the new material could then be successfully used as the basis of sensors that can be permanently installed in in nuclear power plants to continuously monitor the integrity of key components, such as vessels and pipes containing nuclear materials. The sensors would greatly enhance safety and reduce the operation and maintenance costs of the plant, leading ultimately to cheaper electricity.

The aim of the project is to design, build, test and demonstrate a prototype ultrasound transducer that can be used in structural health monitoring, flow measurement and rangefinding applications in the temperature range 200 to 450°C. Such devices are required by the nuclear, oil & gas, industrial controls and aerospace industries. As currently available piezoelectric elements cannot operate beyond 250°C, the prototype will be based on a recently developed high temperature piezoelectric ceramic proprietary to the company. The project will identify acoustic matching and damping layers, compatible with the piezoelectric ceramic and the proposed applications, that can withstand the temperature range of operation and will identify techniques for making robust electrical connections to the active element. The prototype will be tested in the context of structural health monitoring and range-finding applications within the temperature range of interest.
