abstract

This paper presents concepts for Shape-Shifting Surfaces (SSSs), i.e. surfaces that retain their effectiveness as physical barriers while undergoing changes in shape. These shape changes could be motions like expanding, shrinking, twisting, encircling, wiggling, swallowing or constricting that make the surface more effective at performing its function. The SSSs are a novel concept, and are composed of tiled arrays of polygonal cells, each cell consisting of specifically-designed compliant flexures attached to specifically-shaped overlapping thin plates or shells. Applications for such surfaces are anticipated at the micro-scale in cellular engineering and at the macro-scale for biomedical applications, recreational uses, national security, and environmental protection; each will be stem from the foundational concepts described in this paper.
