The overall impedance seen by the piezo actuator driver is still only 1 Ω. This enables a low-voltage amplifier to drive 10-A p-p current through the LCR tank. With this method, the high-current ...

From Equation 2, the current (I) is proportional to voltage (V), capacitance (C), and frequency (f). Let’s use an example. For a high-frequency piezoelectric actuator whose capacitance is 1.1uF, the ...

Driving the PICA series high-force piezo actuators it can provide forces in the 10 kN range to move very heavy objects fast and with nanometer precision. The amplifier’s bipolar driver circuit ...

Piezoelectric materials sometimes seem magic. Apply a voltage to a piezoelectric ... And the LEGS (and similar Inchworm actuator) allows relatively quick, high force, and high resolution motion.
