Liquid crystal elastomer actuator with serpentine locomotion

A snake-mimic soft actuator composed of a bilayered liquid crystal elastomer ribbon and two serrated feet is reported in this work. Under repeated on/off near-infrared light irradiation, this actuator can move forward relying on a reversible shape morphing between S-curve structure and reverse S-cur...

Description
Summary:A snake-mimic soft actuator composed of a bilayered liquid crystal elastomer ribbon and two serrated feet is reported in this work. Under repeated on/off near-infrared light irradiation, this actuator can move forward relying on a reversible shape morphing between S-curve structure and reverse S-curve structure, which is similar to the serpentine locomotion of snakes. In this manuscript, we describe a snake-mimic soft actuator with serpentine locomotion, which can move forward relying on a reversible shape morphing between S-curve and reverse S-curve structures.
