Abstract
This invention provides a light response material. In one embodiment, said light response material comprises: a) a hydrogel of sufficient fracture toughness to accumulate elastic energy for actuation prior to fracture; and b) a photothermal material dispersed in said hydrogel capable of initiating phase transition of water inside said hydrogel from liquid to vapor when irradiated with light to cause accumulation of said elastic energy.
