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 […]
