Piezoelectric ultrasonic transducers come in a variety of sizes, including disks, plates, and tubes, as well as varied levels of performance. By utilizing various piezoceramic materials, electrodes, and assembly techniques, they can be modified to meet application needs. They are present anywhere ultrasound is required, including in numerous medical applications, structural monitoring, and flow metering.
While piezo bending actuators can accomplish displacements up to millimeters, piezo actuators can be found in stacked and multilayer variants, in various force classes, and for displacements up to a few hundred micrometers. They are indispensable in applications ranging from industrial manufacturing or dispensing to ultra-precision positioning thanks to their fundamental characteristics like millisecond response time, high dynamics, and practically limitless resolution.
