Provided are a shape changeable material and a shape changeable electrode including the same, wherein a material having a 2-dimensional (2D) shape obtained when the material is activated by a predetermined stimulus using structural and hierarchical characteristics of the shape changeable material is provided. The shape changeable material provides a material that has various 2D inherent shapes by changing a hierarchical structure of displacement units or a joint pattern, is used as a flexible material or a stretchable material, and may be closely adhered on a curved surface without a lifting. Also, by further forming a coating layer having electric conductivity, an electrode having characteristics of the shape changeable material may be provided.
