Ultrasonic transducers: materials and design for sensors, actuators and medical applications

Ultrasonic transducers are key components in sensors for distance, flow and level measurement as well as power and other applications of ultrasound. Ultrasonic transducers reviews recent research in the design and application of thisimportant technology. Part one provides an overview of materials and design of ultrasonic transducers. Piezoelectricity and basic configurations are explored in depth, along with electromagnetic acoustic transducers, and the use of ceramic, thin film and single crystals. Part two goes on to investigate modelling and characterisation, with performance modelling, electrical evaluation, vibrometry and optical visualization all considered in detail. Applications of ultrasonic transducers are the focus of part three, beginning with a review of surface acoustic wave devices and air-borne ultrasound transducers, and going on to consider ultrasonic high temperature and flaw detection systems, power, biomedical and micro scale ultrasonics, therapeutic ultrasound devices, piezoelectric and fibre optic hydrophones, and ultrasonic motors. With its distinguished editor and expert team of international contributors, Ultrasonic transducers is an authoritative review of key developments for engineers and materialsscientists involved in this area of technology as well as in its applicationsin sectors as diverse as electronics, wireless communication and medical diagnostics.
