A novel asymmetrical flexible piezoelectric microgripper based on flexure hinges is designed and studied to meet the requirements of micro-assembly of micro-tubes whose diameter is 100~ 200 μm.The gripping displacement
gripping force and gripping precision of microgripper are analyzed by theoretical calculation and FEA.The piezoelectric actuator is used as input driver of the microgripper.The experimental results verify the correctness of the theoretical calculation and the FEA.The displacement amplification ratio of the asymmetric flexible piezoelectric microgripper is 4.55.Compared with the results of FEA and theoretical calculation
the errors are 4.22 % and 8.43 %
respectively.The validity of the design is verified.
