Fig. 2.
Self-folding experiments on nets with varying Vc and Rg. Optical and SEM images showing photolithographically fabricated panels connected by solder hinges and the corresponding self-folded 3D structures respectively. (A–F) Dodecahedra in the order Vc = 2, 6, and 10, and Rg = 1,102.2, 800.9, and 693.7 μm, respectively. (G–L) Truncated octahedra in the order Vc = 2, 7, and 12, and Rg = 1,306.3, 912.7, and 795.0 μm, respectively. (M–R) Icosahedra in the order Vc = 26, 38, and 50, and Rg = 711.1, 514.6, and 445.4 μm, respectively. (Scale bar: 300 μm.)
