PI (Physik Instrumente), a leading 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 novel stress reduction and encapsulation technologies that increase lifetime by several orders of magnitude both in static and dynamic applications, addressing key lifetime mechanisms common to other piezoelectric actuators.
For more information, see US Patent No. 7,449,077 Method for the production of monolithic multilayer actuator made of a piezoceramic or electrostrictive material and external electrical contact for a monolithic multilayer actuator.
Typical applications for piezoceramic actuators include:
