Abstract
A substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.
