According to the present invention, provided is a bidirectional stable structure with polymer sheets having a first shape bent in one direction to maintain stability and a second shape bent in the opposite direction to maintain stability. The bidirectional stable structure with polymer sheets overlaps and bonds a first polymer sheet (10) deformed by being pulled in one direction and a second polymer sheet (20) deformed by being pulled in the opposite direction, so that the first polymer sheet (10) and the second polymer sheet (20), respectively, have a first shape and a second shape due to residual tensile stresses and residual strain rates. |
