PI Ceramic Manufacturing & Assembling Technologies

Assembled Piezo Actuators, Innovative Actuator Configurations

PI Ceramic provides a great variety of innovative piezo actuator configurations, an ideal basis for further integration and customization. Multilayer actuators come in all kinds of shapes and geometries, even stacks with aperture are available in multilayer configuration. For high force applications classical actuators made from layers of bulk material are available, in stacked or bimorph bender configurations. 

Actuators can be equipped with temperature sensors or position feedback sensors to make them suitable for repeatable closed-loop positioning with nanometer accuracy. Piezo actuators are often integrated into mechanical systems, fast switches, valves, pumps or positioners where lever amplification increases the travel range of the piezo ceramic element. Flexure guiding systems then provide high stiffness and minimize the lateral offset. 

Piezo Technology Fundamentals 

Flexure Assemblies / Preloaded Actuators / Levers / Nanopositioners 

PICMA® piezo actuators from PI Ceramic are the key component for nanopositioning systems from Physik Instrumente (PI). 

They are supplied in different levels of integration: As simple actuators with optional strain gauge sensors, encased with or without preload (for tensile forces), with lever amplification for increased travel, through to high-performance nanopositioning systems where piezo actuators drive up to six axes by means of zero-wear and frictionless flexure guides. 

Piezo Electric Motor Assemblies 

Piezo ceramics are the drive element for PI's multiple lines of piezomotors. PILine® piezo ultrasonic motors allow very dynamic motion and can be packaged in extremely small positioners. 

Piezo stepping drives provide high forces and picometer resolution. The patented NEXLINE® and NEXACT® drives from PI are based on coordinated motion of longitudinal, shear and bender elements. 

PIShift® drives are based on the stick-slip effect and were designed for cost-sensitive applications.

Extreme Reliability: When 10 Billion Cycles are not Enough 

PICMA® actuators were tested by NASA's Jet Propulsion lab and selected for the Mars Mission. The actuators had to undergo rigorous testing surviving 100 Billion cyles (100,000,000,000) without failures. They are employed in the ChemIn instrument on the Mars Rover Curiosity

No other piezo supplier can provide quality and innovative actuator solutions similar to PI Ceramic.

Miniaturized Piezo Transducers: Tubes, Plates, Rings, Benders

The ongoing miniaturization of piezo transducers opens up new opportunities in medical device manufacturing. PI’s piezo transducer division PI Ceramic has experience in the design and manufacture of miniaturized piezo transducers with both traditional pressing and multi-layer tape casting technology.

Components with external dimensions below 1mm can be produced. Miniaturized sensor and actuator elements can be found in novel scanning catheter endoscopes or in active implants that regulate the internal eye pressure.
