KHZ Medical specializes in the design and building of ultrasonic transducers for medical applications. To-date, KHZ Medical has designed transducers at 21, 28, 33, 40, 42, 70, 125 and 140 kilohertz, but we are happy to design to your specific needs. We make high power Langevin-stack design transducers (often called sandwich transducers) and we specialize in high-power applications. We model our transducers with both finite element analysis (FEA) and lumped-mass models to provide the most reliable and efficient designs available. Our transducer development expertise extends back to our former parent company, Cybersonics and Blackstone Ultrasonics, with over 40 years of development history and expertise.
