Design of the Piezoelectric Actuator with Double Driving Tips
International Journal of Automation and Smart Technology, 2013 The general operation of a piezoelectric ultrasonic resonant actuator is to convert the cyclic motion of the piezoelectric plate to a linear motion at the rotor or slider.

Design of a Low-Frequency Harmonic Rotary Piezoelectric Actuator
Actuators, 2020 Piezoelectric actuators usually operate under a high frequency driving signal. Here we report a harmonic rotating piezoelectric actuator by coupling a harmonic wave generator and a friction rotor, in which the actuator can be actuated by a low-frequency ...

Piezoelectrically actuated time-averaged atomic microtraps [PDF]
Applied Physics Letters, 2012 We present a scheme for creating tight and adiabatic time-averaged atom-traps through the piezoelectric actuation of nanomagnetic structures. We show that potentials formed by the circular translation of magnetic structures have several advantages over conventional rotating-field techniques, particularly for high trap frequencies.
