The invention provides an electrically-driven continuous carbon fiber reinforced shape memory polymer deformation skin capable of designing resistance. The electrically-driven continuous carbon fiber reinforced shape memory polymer deformation skin comprises a shape memory polymer matrix and at least one non-linearly arranged continuous carbon fiber, and the shape memory polymer matrix is coated outside the continuous carbon fiber. According to the scheme, the non-linearly arranged continuous carbon fiber reinforced shape memory polymer deformation skin is used, and under the condition that the skin is deformable, compared with pure filling particles or short fibers, the mechanical property of the skin is further improved; the continuous carbon fibers and the conductive particles serve as reinforcing bodies and conductive networks, and function integration can be achieved; and the resistance value of the carbon fiber is designed by adjusting the length of the continuous carbon fiber, Joule heat is transmitted through the conductive particles according to the use condition, it is ensured that the resistance value of the skin is matched with the applied voltage, and the shape memory polymer can be prevented from being damaged due to instantaneous high temperature while the skin is rapidly heated.
