Development of Highly Reliable Multilayer Piezo Actuators White Paper

PI (Physik Instrumente) published a white paper on the development and test of highly reliable multilayer piezo actuators. The white paper describes the development and lifetime tests of ceramic encapsulated actuators under different operating conditions (DC and AC). The actuators are compared to polymer coated piezo ceramic actuators in long term tests. Equations and graphs for lifetime calculation under different operational and environmental conditions and special internal electrode designs for stress reduction are discussed.
