The composition of a crosslinked azobenzene liquid-crystalline polymer and a flexible polymer film can provide a variety of simple devices that can walk in one direction like an 'inchworm' and move like a 'robotic arm' induced by light. The Royal Society of Chemistry 2009.

(Figure Presented) Bending over backwards: Ferroelectric liquid-crystalline (LC) elastomer films with a high LC order and low glass transition temperature bend when irradiated with light (see picture). At 366 nm the films bend toward the actinic light source along the alignment direction of the mesogens, and they recover their initial flat state after exposure to visible light. The mechanical force generated by photoirradiation reaches about 220 kPa.
