This technology is a photo-responsive deformable structure and a method for operating it, which utilizes the bending deformation induced by the cis-trans isomerization of azobenzene liquid crystal polymers via light irradiation as a driving force.
Existing intelligent composite actuators have limitations in that they require heat supply, electrical current, or direct mechanical tension to operate, leading to a high dependency on external devices and complex system requirements.
This technology proposes a method utilizing a multi-polymer film structure containing photo-responsive azobenzene liquid crystal polymers and adhesive supports at the ends of the body. By inducing reversible bending deformation through irradiation with specific wavelengths of light, it generates adhesion to the ground, release, and propulsion, allowing for active movement control using only light energy without mechanical contact. Applicable to microrobots, smart materials, and light-driven actuators, it presents new possibilities for next-generation drive systems that control movement using only light, without the need for power sources or wiring.
