Disclosed is a loop linked smart morphing actuator. The actuator includes a first area morphed in a first pattern and a second area morphed in a second pattern according to an external signal. The first area includes a first unit cell morphed in a first direction. The second area includes a second unit cell morphed in a second direction. The first unit cell and the second unit cell may be configured in a loop type knit structure. The second direction is opposite to the first direction, the second pattern is a pattern which has a symmetrical relationship with the first pattern and is provided opposite to the first pattern. In regard to a structure or a shape, provided is an actuator including a knit structure for realizing various driving forms which cannot be predicted through predetermined first and second patterns or a simple combination thereof.
