Abstract:
We designed guest-filled, twist-spun carbon nanotube yarns having useful topological complexity as
electrolyte-free muscles that provide fast, high- force, large-stroke torsional and tensile actuation.
Over a million reversible torsional and tensile actuation cycles are demonstrated, wherein a muscle
spins a rotor at an average 11,500 revolutions/minute or delivers 3% tensile contraction at 1,200
cycles/minute. This rotation rate is 20 times higher than previously demonstrated for an artificial
muscle and the 27.9 kW/kg power density during muscle contraction is 85 times higher than for
natural skeletal muscle.
