PI receives US patent

News
The company receives US patent for piezo actuator technology enabling higher reliability.
PI (Physik Instrumente), a manufacturer of piezo actuators and precision motion control equipment has received a United States patent for its development of innovative multilayer ceramic actuators. PI’s exclusive PICMA piezo ceramic actuators are based on the novel stress reduction and encapsulation technologies which increases longevity both in static and dynamic applications, addressing key lifetime mechanisms common to other piezoelectric actuators.

For more information, see U.S. Patent No. 7,449,077 “Method for the production of monolithic multilayer actuator made of a piezo-ceramic or electro-strictive material and external electrical contact for a monolithic multilayer actuator.”

Typical Applications for Piezoceramic Actuators are semiconductor test & measurement, life sciences, nanomanipulation, aerospace & astronomy, optics, photonics & metrology, spectroscopy, microscopy, AFMs, NSOM, lithography, nanopatterning, motion control, micro steppers, voice coils and data storage microactuation.
