Also, when working under the DC non-resonance working mode, the maximum output displacement was 2.62 um. And the measurable minimum output displacement was 50 nm, which can reach smaller in theory. The correlation coefficient between the output displacement and the input DC voltage is 0.998, which was good for the control of the actuator under the non-resonance working mode. This piezoelectric actuator can accomplish linear position quickly and accurately in a large stroke with simple structure using bending modes.
