Abstract
A gripper and a driving method using the same are disclosed, wherein an actuator has a configuration combined with a piezoelectric operating unit and a bending structure, whereby an amount of variation of a gap between fingers are amplified more than that of the piezoelectric operating unit by generating a movement of the fingers perpendicular to a movement direction of the piezoelectric operating unit, and wherein the gripper having arms including a strain gauge sensor can precisely measure a force applied to a micro object.
