PICA Shear Actuators from PI (Physik Instrumente) L.P.


The unique PICA™ Shear piezo actuator series are exclusively available from PI. These devices are extremely compact and feature sub-nanometer resolution and ultra-fast response. They come in a variety of geometries providing displacements to 10 µm. Possible applications for these devices are e.g. scanning microscopy, or in motor drives.

  • Compact Single- and Multi-Axis Actuators
  • X-, XY-, XZ- and XYZ-Versions
  • High Resonant Frequencies
  • Extreme Reliability >109 Cycles
  • Picometer-Resolution / Sub-Millisecond Response
  • UHV Versions to 10-9 hPa
  • Non-Magnetic and Clear Aperture Versions

High Stiffness and High Displacement
PICA™ Shear actuators exhibit high stiffness, both parallel and perpendicular to the motion direction. Based on the piezoelectric shear effect, the PICA™ Shear X and XY actuators show almost twice the displacement amplitudes of conventional piezo 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.

High Reliability under High Duty Cycles, Low Power Requirements
PICA™ Shear 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.

Short Leadtime for Standard & Custom Designs
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 at a very attractive price, even for small quantities. Some of our custom capabilities are listed below:
  • Custom Materials
  • Custom Voltage Range / Custom Displacement
  • Clear Aperture
  • Custom Load / Force Ranges
  • Custom Flat or Spherical Endplates (Metal, Ceramics, Glass, Sapphire, ...) / Optical Surface Quality
  • Extra-Tight Length Tolerances
  • Combination with Piezoelectric Shear Sensors (no Pyroelectric Effect)
  • Low-Temperature Designs, Down to Liquid-He
  • Vacuum Compatible and Non-Magnetic Versions
Because all piezoelectric materials used in these actuators are manufactured at PI Ceramic, leadtimes are short and quality is outstanding. All standard and custom actuators are delivered with performance test sheets.
