Title:

ACTUATOR USING PHOTO-RESPONSIVE SHAPE-CHANGING CONSTRUCT AND METHOD OF DRIVING SAME

Document Type and Number:

WIPO Patent Application WO/2020/027379

Kind Code:

A1

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.
