PI’s PICMA actuators product family, features the P-080.
PI (Physik Instrumente) L.P., a manufacturer of piezo systems and precision motion and positioning equipment, recently introduced the P-080 tubular piezo stack, the newest member of the high reliability PICMA family of piezo actuators. Piezo actuators are based on solid-state motion effects and are used in applications that require any or all of the following attributes: high speed, high force, and virtually unlimited resolution.
Tubular Stacks vs. Piezo Tubes
Tubular stacks combine the advantages of stack actuators with the versatility of piezo tubes. Stacks are significantly more robust than tubes and provide much higher stiffness and forces as well as longer travel ranges. P-080 stacks come in displacement ranges of 5, 11 and 25 microns with up to 850N blocking force.
Who’s Sensitive?
Conventional, polymer-insulated piezo actuators are sensitive to environmental conditions, especially humidity and temperature. Based on a patented, ceramic-encapsulation process developed by PI’s piezo division PI Ceramic, PICMA multilayer piezo stack actuators are significantly more durable and reliable. PI’s actuators are a manufactured in a cofirming process as monolithic blocks that can be combined to achieve longer displacement range.
Welcome to the Family
The P-080 joins a large family of piezo actuators including miniature chip actuators (2x2x2mm) and high-force actuators providing several 1000lbs of force. As a multilayer stack actuator, the through-hole of the P-080 is ideal for preloading or as aperture for optical applications. Microsecond response, sub-nanometer resolution and the low operating voltage, along with minimal power consumption while holding the position, make the P-080 ideal for many precision motion tasks in optics, semiconductors, photonics, and precision engineering applications.

Proven Reliability on Mars Rover 100 billion successful cycles, no failure
Having passed extensive NASA performance qualifications and testing, PI’s actuators are used in the sample analysis system of the CheMin instrument in the Mars rover Curiosity. “Quality awareness and careful process monitoring from powder to dispatch really do pay off”, says Dr. Karl Spanner, CEO of PI, Karlsruhe, Germany. “We ourselves have been using the PI Ceramic PICMA multilayer actuators for more than ten years in our piezo nanopositioning systems.”
