Abstract: The piezoelectric actuator of the present invention has at least one ceramic component. The ceramic component has an output surface and two driving surfaces. The ceramic component has a height and the output surface is rectangular in shape, wherein the length of the short axis side of the output surface is shorter than the height. Therefore, when a pulse wave input voltage is applied on the driving surfaces, the output surface generates an elliptical motion.
