Piezoelectric ultrasonic transducers are available in a wide range of shapes like disks, plates or tubes, and different performance levels. They can be adapted to application requirements by using different piezoceramic materials, electrodes, and assembling technology. They are present wherever ultrasound is needed, like in flow metering, structural monitoring, and many medical applications.
Piezo actuators are available as stacked and multilayer versions, in different force classes and for displacements up to some hundred micrometers, while piezo bending actuators achieve up to millimeters. Their basic features like millisecond response time and high dynamics combined with virtually unlimited resolution make them indispensable in applications from industrial production or dispensing to ultra-precision positioning.
