FAQ: What are low voltage piezo actuators, and where are they used?
When voltage is applied to a piezo ceramic material, the material experiences a displacement (expansion or contraction) per the inverse piezoelectric effect. The amount of displacement that results from the applied voltage depends on thickness of material. Thus, for a given displacement, a thinner material requires a smaller voltage than a thicker material. Low voltage […]

FAQ: What are other options for nanopositioning besides piezo actuators?
Nanopositioning—positioning on the scale of one-billionth of a meter—is a common requirement in semiconductor and medical applications, such as metrology, scanning, dispensing, and pumping. But consistently achieving nanometer-level resolution is beyond the scope of most devices that use mechanical rolling or recirculating elements. Case in point: the most common solution for nanopositioning applications is the piezo motor […]

FAQ: How do linear stepper and linear ultrasonic piezo motors differ?
There are a number of ways in which piezo ceramics can be used to create linear motion, providing any combination of high speed, long travel, and high force. Two common types are linear stepper and linear ultrasonic piezo motors. Both use the inverse piezoelectric effect to activate a rod or pusher and create linear motion, […]
FAQ: Where are linear stepper piezo motors suitable?
There are several types of piezo motor that provide linear motion, with one of the most widely used being the linear stepper piezo motor. These devices harness the coordinated motion of multiple piezo elements to produce virtually unlimited travel with high resolution and very high stiffness. Construction and operation In the linear stepper design, multiple […]
