The driver exploits the fact that, at resonance, current and voltage is in phase for a piezoelectric transducer. By locking the driving signal to the current feedback signal, i.e. adjust the driving ...

The compact PILine ultrasonic piezoelectric linear encoders and motors make obsolete both the lead screw duct and the bulky, flanged stepper motors of traditional stages. Furthermore, the piezomotors ...

Piezoelectric materials have many applications, including sonar technologies and devices that generate and sense ultrasound waves. But for these devices to efficiently generate sonar or ultrasound ...
