dc.description.abstract | Curved bilayer plates with soft and stiff segments are widely observed in nature, such as plant cell walls, insect exoskeletons and reptile skins. We report an unusual biaxial and bidirectional bending of microfabricated bilayer plates composed of a swellable, photopolymerized poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAM-AAc) layer and a regular array of SU-8, a stiff, non-swellable epoxy. Hydrogels such as pNIPAM-AAc exhibit large and reversible swelling in water in response to a temperature change through the lower critical solution temperature (LCST). The stimuli responsive behavior was harnessed in the composite structure containing materials with mismatched swelling and elastic properties to produce actuation and mechanical motion. The structure undergoes reversible bending along two different axes in response to a temperature cycle through the LCST. Cooling the patterned bilayer structure leads to bending upwards about one axis, while heating leads to bending downwards about a different axis, 90 | - |
