Abstract: Disclosed are a design and manufacturing method for a three-dimensional electromechanical adhesive surface structure capable of adhesive force manipulation and tactile sensing by using 3D printing. The three-dimensional electromechanical adhesive surface structure includes: a body; a plurality of three-dimensional micro pillar structures which are attached to the body at a certain angle; and a wire which supplies voltage to the plurality of three-dimensional micro pillar structures. The three-dimensional micro pillar structure includes: a pillar which is attached to the body at a certain angle and is formed integrally with the body; a conductive material which is applied to surround the pillar; and an insulating material coated to surround the conductive material in order to be insulated from an opposite surface. The voltage supplied through the wire is supplied to the conductive material. A passage for providing the wire is formed under the plurality of three-dimensional micro pillar structures of the body. As a result, a technology allowing a robot to recognize, feel, and move an object beyond the human level is implemented, so that it is possible to maximize the convenience and efficiency.
