Abstract: A shape changeable material includes a hierarchical structure including a basic displacement unit that includes a basic separation structure and basic unit cells, and a higher level displacement unit located inside the basic unit cell and including higher level unit cells distinguished from each other by a higher level separation structure, in which a separation structure including the basic separation structure and the higher level separation structure includes joints connecting neighboring unit cells to each other. By further forming a coating layer having electric conductivity, a shape changeable electrode includes a supporter that includes a shape changeable material, and the electric conductive coating layer provided on the supporter.
