Light‐responsive microactuators composed of vertically aligned carbon nanotube (CNT) forests mixed with poly(N‐isopropylacrylamide) (PNIPAM) hydrogel composites are studied. The benefit of this composite is that CNTs act as a black absorber to efficiently capture radiative heating and trigger PNIPAM contraction. In addition, CNT forests can be patterned accurately using lithography to span structures...
