Circular Piezo Actuators suit highly dynamic processes.

Press Release Summary:

Based on multilayer and ceramic encapsulation process, P-088 Circular PICMA® Piezo Actuators, Chips, and Tubular Stacks offer microsecond response time, sub nanometer resolution, and resonant frequency to 68 kHz. PICMA® ceramic technology is applied to PD0xx miniature annular PZT chips with outer diameters from 5–16 mm and inner diameters of 2.5–8 mm. Largest 16 mm unit delivers 6,000 N of blocking force in circular form and 4,400 N in annular shape. Travel range of 2 µm is achieved at 100 V.

Original Press Release:

New Circular Piezo Stack Actuators and Miniature Ring Actuators are Highly Reliable, Produced by PI

Auburn, MA – Motion control and piezo systems expert PI (Physik Instrumente) L.P. introduces a new line of round multilayer actuators in its proprietary PICMA® ceramic series and expands its current line of rings and round chips with larger dimensions. Proven reliability for high performance and long lifetime, PI’s actuators are ideal for industry and research, including laser tuner, micro-dispensing, and life sciences.

Flexible Scaling, Superior Lifetime

With microsecond response time, sub nanometer resolution, and very high forces, the P-088 circular series PICMA® piezo actuators, chips and tubular stacks now complement the successful family of square PICMA® actuators that currently find use on the Mars Rover Science Lab after surviving 100 billion cycles of stress testing by NASA/JPL. The new actuators are based on the same multilayer and ceramic encapsulation process, and can be stacked from smaller segments to allow even faster adaptation for OEM needs with a short delivery time. Low operating voltage and resonant frequency up to 68kHz make these actuators well suited for highly dynamic processes. Actuators are available in a variety of shapes and with different options, including UHV compatible versions with solderable contacts.

Circular and Annular, Ultracompact, Stackable, Variable Diameters

PICMA® ceramic technology is applied to the PD0xx series of miniature annular PZT chips with outer diameters from 5mm to 16mm and inner diameters of 2.5mm to 8mm. The largest diameter, 16mm, delivers 6000N (1300lbs) of blocking force in circular form and 4400N in annular shape. Travel range of 2µm is achieved at 100V.

Technology Proven In Space

PI’s proprietary PICMA piezo ceramics were successfully tested for 100 billion cycles by NASA/JPL which qualified them to be used in the Mars Rover’s instrumentation and testing equipment. Four years after Curiosity first landed on the red planet, PI products are still going strong at peak performance and reliability. PICMA technology integrates ceramic insulation that is polymer-free, humidity resistant, and able to tolerate a temperature range of -20 to 80 C.
