Bioinspired Stimuli‐Responsive Hydrogel with Reversible Switching and Fluorescence Behavior Served as Light‐Controlled Soft Actuators

Stimuli‐responsive materials with multiple functions occupy a significant position in the research of bionic artificial intelligence materials. It is a challenge to integrate rapid shape deformation and color change synergistically by a simple method in the same system. Herein, an effective strategy to develop an anisotropic bilayer hydrogel actuator with unified complex deformation and color change is proposed via combining the near‐infrared...
