PI Ceramic Presents New Results on Piezo Actuator Reliablilty at ACTUATOR 2006The reliability of multilayer piezoelectric actuators is an important issue for the extension of their use. Two different operating conditions have to be distinguished: AC-operation (dynamic) and DC operation (static). The paper explains DC- and AC-degradation mechanisms as well as the unique design of the PI Ceramic PICMA cofired actuators.
