A shape‐memory, fiber‐shaped supercapacitor is developed by winding aligned carbon nanotube sheets on a shape‐memory polyurethane substrate. Despite its flexibility and stretchability, the deformed shapes under bending and stretching can be “frozen” as expected and recovered to the original state when required. Its electrochemical performances are well‐maintained during deformation, at the deformed state and after the recovery.
