Multilayered piezoelectric actuator used in e.g. machine tools, consists of several piezoelectric elements made of lead zirconate titanate (PZT) ceramic, which are alternately arranged at opposite sides of several internal electrodes

摘要

The piezoelectric actuator consists of several piezoelectric elements made of lead zirconate titanate (PZT) ceramic, which are alternately arranged at the opposite sides of several internal electrodes. The internal electrodes are mutually contacted to the common external electrode. Two piezoelectric actuators are piled on each other such that their end-side feet are connected to the common base.
