Abstract
Ultrasonic technology applications have been researched in a wide range of fields, from sonochemistry and industrial cleaning to medical tools and agriculture. However, the largest limitation in many of these applications is the inability of existing technology to provide a single transducer with sufficient power to make important laboratory sonochemical processes commercially successful. TERFENOL-D magnetostrictive material technology enables a next-generation high power ultrasonic transducer. Until very recently, generating high power at high frequency has been unexplored territory for giant magnetostrictive materials. But the unique attributes of these materials, such as energy density and thermal handling capabilities, are being used to develop a wide variety of transducers, devices and systems for existing as well as new ultrasonic applications. These unique material attributes combine with novel magnetic field generation, transducer, acoustic transmission and coupling concepts to meet the challenges of power, size, thermal, efficiency and reliability requirements of transducers and system for many ultrasonic applications. Polymer processing and curing, enhanced oil and gas recovery, seed sonication, surgical tools, and beer foaming are just some of the many applications where ultrasonic magnetostrictive technologies are overcoming barriers to provide improved solutions.
