Abstract
The Langevin transducer is a common configuration of device in power ultrasonics applications, across medical and industrial ultrasonics. It has been widespread in surgery and dentistry, and also for industrial applications including welding. The configuration relies on tuning to a single resonance frequency, however there is growing demand for resonance tuneability. For example, in surgery it is common to replace cutting tips for operation on different target materials. By utilising a shape memory material instead, whose elastic properties can be shifted with temperature or stress, there is the opportunity to remove this need for replacement. In this study, a Langevin transducer is fabricated and characterised, where the end-masses are manufactured from the shape memory alloy Nitinol. The prototype is characterised, showing resonance tuneability across a relatively small temperature difference of 30°C, showing potential for practical application.
