Large‐Deformation, Multifunctional Artificial Muscles Based on Single‐Walled Carbon Nanotube Yarns

Helical shape, wax-infiltrated SWNT yarns are fabricated into multifunctional electromechanical actuators to produce large tensile contraction and unique functions including dragging an object, changing shape, self-twisting, and tightening an object, all of which can be generated in simple configurations under small voltages.
