Project Description

Applied Physics PhD - High Frequency Flexural Ultrasonic Transducers (HiFFUTs)

Flexural transducers have been utilised for a variety of applications, most notably as car-parking sensors. Using current technology, flexural transducers are only capable of operating in ambient atmospheric conditions up to frequencies of approximately 50 kHz. Despite the fact that these sensors are produced in their millions, remarkably little is understood about their properties, and we have a unique opportunity to use our understanding of the physics involved to make significant new discoveries and innovations in ultrasonic sensor technology.

Flexural transducers which can operate effectively at higher frequencies are highly desirable and would enable us to probe new areas of scientific metrology, and in this project we will design and construct high frequency sensors that can withstand higher pressure and temperature levels associated with more hostile environments encountered in many real world applications. The major objective of this research is the to understand the physics behind these transducers and then exploit that understanding to development of such flexural transducers, known as high-frequency flexural ultrasonic transducers (HiFFUTs).

This PhD project is part of a team effort at Warwick involving a small team of researchers funded by a £1.2M EPSRC research grant to undertake fundamental research into HiFFUTs. You will be based in the Ultrasonic Group in the Physics Department at the University of Warwick (https://www2.warwick.ac.uk/fac/sci/physics/research/ultra/), which has an excellent record in developing innovative research and translating it into practical technology. The Ultrasound Group is an Applied Physics research group of approximately 20 people. We publish in the leading Applied Physics journals and collaborate extensively with industry, with many of our research outputs ending up as real world devices.

Candidates should hold or expect to hold a 1st (or high 2.1) in Physics, Engineering or related subject area. For more information, please contact Professor Steve Dixon ( / T: 02476 573877).

Funding Notes

A full 3.5 year studentship for UK students and EU students is available. Applications are accepted at any time.

The Physics department is proud to be an IOP Juno Champion and a winner of an Athena Swan Silver Award, reflecting our commitment to equal opportunity and to fostering an environment in which all can excel.
