Introduction to Ultrasonic Drivers

The most common type of ultrasonic actuator is the bolt-clamped Langevin transducer, shown in the image below. These actuators consist of piezoelectric discs sandwiched between metal electrodes. The centre bolt preloads the structure with a compressive force that is sufficient to prevent tensile forces during operation.
