Shape changeable material having inherent shapes using hierarchical structure and electrode having same

A shape changeable material having:

• a hierarchical structure comprising a basic displacement unit comprising a basic separation structure and basic unit cells, and
• a higher level displacement unit located inside the basic unit cell and comprising higher level unit cells distinguished from each other by a higher level separation structure;
• wherein a separation structure comprising the basic separation structure and the higher level separation structure comprises joints connecting neighboring unit cells to each other, wherein the joints have a joint pattern in which a joint shape of an outer joint contacting an outer portion of a displacement unit and an inner joint not contacting the outer portion of the displacement unit is alternately repeated;
• and
• inherent shapes resulting from hierarchical joint patterns included in higher level displacement units and the hierarchical structure, and activated by rotation movement of the basic unit cells and the higher level unit cells and relative location changes between the unit cells.
