P-111 – P-151 PICA™-Shear Piezoelectric Actuators — Compact Multiaxis Motion
PICA™-Shear series multi-axis piezoelectric actuators are only available from PI / PI Ceramic. These devices are extremely compact and feature sub-namometer resolution and ultra-fast response. They are available in a variety of geometries providing displacements to 10 µm.
High Stiffness, High Duty Cycles
Low Power Requirements, Ultra-High Reliability, Long Travel Ranges Custom Actuators
Application Examples:
PICA™-Shear piezoelectric actuators exhibit high stiffness, both parallel and perpendicular to the motion direction. Based on the piezoelectric shear effect, PICA™-Shear X and XY piezoelectric actuators show almost twice the displacement amplitudes of conventional stacked piezoelectric actuators at the same electric field. Consequently they can be made smaller and have higher resonant frequencies. This results in reduced power requirements for a given induced displacement in dynamic X- and Y-axis operation.
PICA™ piezoelectric actuators are specifically designed for high-duty-cycle applications. All materials used are specifically matched for robustness and lifetime. Endurance tests proved consistent performance even after billions (1,000,000,000) of cycles. The combination of high displacement and low electrical capacitance provides for excellent dynamic behavior with reduced driving power requirements.
All manufacturing processes at PI Ceramic are set up for flexibility. Should our standard actuators not fit your application, let us provide you with a custom design. Our engineers will work with you to find the optimum solution at a very attractive price, even for small quantities.
