Chiroptical 3D Actuators
In article number 2210680, Kwang‐Un Jeong, Seung‐Yeol Jeon, Dae‐Yoon Kim, and co‐workers develop chiroptical 3D smart actuators by assembling cholesteric liquid crystals onto a polymeric gel thin film. Various reversible motions of chiroptical 3D smart actuators are performed by swelling and deswelling of the programmed Janus structures. The newly developed chiroptical 3D...
Examples of anisotropic movement paired with helical geometry abound in the animal and plant kingdoms are used for a variety of reasons, such as diverse social signaling directed at conspecifics or camouflage to avoid predation. Inspired by these natural phenomena, a smart sensor is developed with a chiroptical 3D actuator that can fold, bend, and twist in response to external stimuli, reflecting...
