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.
