Patent ID: 7770951

Claim:
A micro gripper, comprising: a micro gripper jaw composed of first and second structures each oppositely spaced a predetermined distance (d 1 ) apart, in which a penetration hole that enables fluid to flow inside the respective structures is respectively formed, and the penetration hole is respectively exposed on opposite surfaces of the first and second structure, where the first and second structures of the gripper jaw are formed with a first substrate and a second substrate each with the penetration hole formed therein; a force transmission part, connected to the first and second structures of the gripper jaw, configured to transmit a force, to enable the first and second structures of the gripper jaw to grip an object by narrowing the distance (d 1 ) there between; an actuator providing a force to the force transmission part; a fluid supply and suction unit configured to supply the fluid to the penetration hole of the gripper jaw so as to detach the object attached to opposite surfaces of the first and second structures, or suck the fluid from the penetration hole of the gripper jaw so as to enable the first and second structure to strongly grip the object.
