Creeping gel Photosensitive self-oscillating gel to model biological crawling motions

Directed motion seems simple to us, but the coordinated interplay of complex processes is needed, even for seemingly simple crawling motions of worms or snails. By using a gel that periodically swells and shrinks, researchers developed a model for the waves of muscular contraction and relaxation involved in crawling. They were able to produce two types of crawling motion by using inhomogeneous irradiation.
