This work reports a novel design of a micro gripper, in which V-shaped electrothermal actuators are used to create gripping force and a compliant mechanism is integrated to amplify displacements of the actuators. The gripper is designed to handle micro samples of various sizes from 5 m to 50 m by applying appropriate driving voltages. Those voltages are ranged from 5 V to 25 V, which are relatively low in comparison with driving voltages of the electrostatic micro grippers. The compliant mechanism with amplifying ratio , arranged between the actuators and the jaws, is aimed to compensate small strokes of the actuators. Simulation by Finite-Element Analysis has also been carried out to confirm results of the theoretical calculation and designing process. |
