Minaturised, cylindrical ultrasound arrays are showing great promise for applications such as intra-vasculature imaging for peripheral arterial disease, and borescope imaging of internal small pipework for defects or corrosion. However, manufacturing small-scale, high-frequency ultrasound arrays is typically challenging, costly, and time-consuming. Due to being constructed from bulky ceramics, the...Show More
The mass-manufacture of high-resolution ultrasound transducers remains a challenge. This work presents a scalable, additive manufacturing method for producing ultrasound transducers. The thin-film based sensors are easy to assemble, highly customizable, and provide large bandwidth at high frequency. A novel sensor material is deposited on to a flexible substrate using a reactive sputtering method ...Show More
Ultrasonic inspection is the go-to tool for a range of industrial NDE applications. There are, however, severe limitations when applying the technology in high temperature environments. For sectors such as oil & gas and nuclear power this makes the monitoring of assets at elevated temperatures challenging; often requiring costly and inconvenient shutdown. Suitable sensors can be permanently fitted...Show More
