This paper presents a lever-type stick-slip piezoelectric actuator based on the lever amplification principle. The proposed actuator can achieve large strokes, high velocity, and bidirectional actuation with a single piezoelectric stack. The finite element simulation of the lever-type flexible hinge is performed, and the designed prototype is tested. When the voltage is 100 Vp-p, the maximum forward velocity is 7.69 mm/s under the symmetry of 20%. The maximum reverse velocity is 7.12 mm/s under the symmetry of 80%. The maximum forward and reverse displacement deviation within 10 cycles is 0.88 mu m, and the maximum load can reach 105 g. Published by AIP Publishing.
