Patent ID: 8137799

Claim:
An article capable of undergoing stimulus-induced deformation comprising, a polymer gel comprising: a skeleton; and cells dispersed within the skeleton; and a liquid crystal serving as a deformation source selected from the group consisting of 4-pentyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanophenylpyridine, 4-but-3-enyloxybenzoic acid 4-methoxyphenyl ester, and 1-(4-hydroxy-4′-biphenyl)-2-[4-(10-undecenyloxy)phenyl]butane, wherein a mesogenic group of the liquid crystal is bound to a polymer chain of the polymer as a side chain and generates a liquid crystal phase state of an elastomer.
