New paper: Snapping structures by folding forms
Traditional origami folds a flat sheet into a seemingly endless variety of forms. Almost nothing is known about folding curved paper since it is so difficult to make. We developed a technique to fold curved polymer shells, and characterize the behavior of these individual folds. We provide a geometric mechanism that demonstrates that some folds […]
New paper: Self-folding origami
Self-folding microscale origami patterns are demonstrated in polymer films with control over mountain/valley assignments and fold angles using trilayers of photo-crosslinkable copolymers with a temperature-sensitive hydrogel as the middle layer. The characteristic size scale of the folds W = 30 ?m and figure of merit A/ W 2 ? 5000, demonstrated here represent substantial advances […]
