【Abstract】 A new micro step motion mechanism driven by piezo element was developed.This paper introduces the principle of the step motion mechanism.Some experiments were carried out to check the feasibility of realizing step motion.The step and dynamic property of the mechanism was measured.An equation was provided to approximately describe the speed of motion.The experiments show that the mechanism can realize large-range step motion,with a comparatively high speed and a nanometer to micrometer order step.更多还原
