Finger-shaped Ultra-small ‘Gripper’ Robot Developed


SEOUL, Oct. 15 (Korea Bizwire)A finger-shaped ultra-small robotic gripper that ensures accurate measurement even for weak pulse and low heart rate was developed.

A research team of Ajou University said that it developed a finger-shaped ‘soft gripper’ and published the research results in the international academic journal Science Robotics on Thursday.

By using a shape memory polymer, a material that enables adjustment of hardness and softness, the research team developed a gripper that has similar properties to human skin.


The research team also used silver nanowire and laser processing to minimize sensors, thereby reducing the size of the robot to less than 5 millimeters.

By using the newly-developed soft gripper, the research team succeeded in gripping a snail egg with a diameter of 3 millimeters and hatching it by applying heat.

It succeeded in capturing small motions generated during the hatching process. Right after the egg hatched, the research team also measured the heart rate of the snail.
