Ultrasonic Transducers: Materials and Design for Sensors, Actuators and Medical Applications (Woodhead Publishing Series in Electronic and Optical Materials)by Kentaro Nakamura
Synopses & Reviews
Ultrasonic transducers are key components in sensors for distance, flow and level measurement as well as power and other applications of ultrasound. This book reviews recent research in the design and application of this important technology.
Part one provides an overview of materials and design of ultrasonic transducers. It explores piezoelectricity and basic configurations, along with electromagnetic acoustic transducers, and the use of ceramics, thin film and single crystals. Part two investigates modeling and characterization and considers in detail performance modeling, electrical evaluation, laser Doppler vibrometry and optical visualization. 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 goes on to consider ultrasonic high temperature and flaw detection systems, power, biomedical and micro scale ultrasonics, therapeutic ultrasound devices, piezoelectric and fiber optic hydrophones, and ultrasonic motors.
Ultrasonic transducers are key devices for important applications such as medical treatments, non-destructive testing and precision alignment. This book reviews the materials, design and applications of ultrasonic transducers and focuses on recent developments and issues. Part one provides an introduction to the materials and design of ultrasonic transducers. Part two covers modelling and characterization of ultrasonic transducer performance. Part three reviews materials and design while part four contains chapters on applications of ultrasonic transducers in devices and systems, including SAW devices, sensors and actuators and therapeutic ultrasound.
