Implication

Experimental study demonstrates high-speed torsional and tensile actuation in hybrid carbon nanotube muscles, highlighting versatile power sources without electrolytes.

Key Points

To develop high-performance, electrolyte-free artificial muscles capable of rapid, high-force torsional and tensile actuation driven by diverse energy sources.
Fabricated guest-filled, twist-spun hybrid carbon nanotube yarns engineered to operate without liquid electrolytes.
Subjected yarns to electrical, chemical, and photonic stimuli to evaluate torsional rotation, tensile contraction, and cycle life.
Sustained more than 1 million continuous torsional and tensile actuation cycles.
Achieved average rotor rotation speeds of 11,500 revolutions per minute and 3% tensile contraction at 1,200 cycles per minute.
Successfully demonstrated functional applications including torsional micromotors, contractile actuators, and self-powered mechanical sensors.
