3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

Advanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.
