Movie S1
Cold drawing of bimorph fibers to obtain spring structures. Following spring formation, stretched and released fiber-based muscles spontaneously move on a flat surface until equilibrium residual strain is reached.
Movie S2
Manual cold drawing of larger bimorph fibers. Fiber cross-sectional area is 5×3.5 mm2, initial fiber length is 5 cm.
Movie S3
Weightlifting performance of individual and bundled fiber muscles actuated via a heat gun. Fiber cross-sectional area is 300×470 μm2, fiber length is 5 cm.
Movie S4
Stretching a single fiber-based artificial muscle and an artificial bicep made of 100 fiberbased muscles bundled in an oblique fashion. The cross sectional area of the fibers is 300Ã-470 μm2.
Movie S5
An artificial limb mimicking a human arm is driven by a fiber-based muscle actuated via a heat gun. We applied 2 s of heat and followed by a 5 s cooling period. The cross sectional area of the fibers is 300×470 μm2.
Movie S6
A larger scale artificial limb is driven by 2 fiber-based muscles actuated via a heat gun. The muscles were actuated by 2 s of heat application and followed by 5 s cooling intervals. The cross sectional area of the fibers is 300×470 μm2.
