New paper: Self-folding origami

Microsoft Word - Manusript_Self-folding origami 10-6-14.docx
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 μm and figure of merit A/ W 2 ≈ 5000, demonstrated here represent substantial advances in the fabrication of self-folding origami.
