Abstract: The present invention discloses a composite polarization type piezoelectric actuator comprising a ceramic element having a first polarizing region and a second polarizing region, wherein the first polarizing region has a first polarizing direction different from a second polarizing direction of the second polarizing region. When a voltage is applied to the composite polarization type piezoelectric actuator, an end face of the ceramic element is deformed. When a pulse wave voltage is applied to the composite polarization type piezoelectric actuator, the end face of the ceramic element generates an elliptical motion.
