PICA-Shear series multi-axis piezo actuators are only available from PI Ceramic. These devices are extremely compact and feature sub-namometer resolution, ultra-fast response and high force generation. They are available in a variety of geometries providing displacements to 10 µm.
High Stiffness under High Duty Cycles PICA-Shear actuators exhibit high stiffness, both parallel and perpendicular to the motion direction. Based on the piezoelectric shear effect, PICA-Shear X and XY actuators show almost twice the displacement amplitudes of conventional piezo actuators at the same electric field strength. 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.
Ultra-High Reliability, High Displacement, Low Power Requirements PICA 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.
Flexibility: PI Ceramic's Strength All manufacturing processes at PI Ceramic are set up for maximum 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 for your application, at a very attractive price, even for small quantities.
