  • Patent number: 11897184
    Abstract: The present invention relates to a photo-responsive shape-changing structure and a driving method thereof. The photo-responsive shape-changing structure (100) is characterized in that it includes a first body portion (200) including at least one polymer film that undergoes a bending deformation in response to light irradiation, a second body portion (300) including at least one polymer film that undergoes a bending deformation in response to light irradiation, and a connection portion (400) configured to allow the first body portion (200) and the second body portion (300) to be connected to each other, wherein adhesive support portions (500, 600) are formed at one ends of the first body portion (200) and the second body portion (300), which are in contact with the ground (20).

  • Patent number: 11598319
    Abstract: The present invention relates to an actuator using a photo-responsive shape-changing construct, the actuator comprising: a 1-1 polymer film and a 1-2 polymer film, configured to undergo a bending deformation in response to a light irradiation; a first restricting member provided between the 1-1 polymer film and the 1-2 polymer film so as to allow the 1-1 polymer film and the 1-2 polymer film to be connected to each other; and a rotation member configured to rotate as the rotation member, at least in part, is pushed by an end of the 1-1 polymer film along with the bending deformation of the 1-1 polymer film.
