TL;DR: Self-supporting nanotube sheets are initially formed as a highly anisotropic electronically conducting aerogel that can be densified into strong sheets that are as thin as 50 nanometers and the measured gravimetric strength of orthogonally oriented sheet arrays exceeds that of sheets of high-strength steel.

TL;DR: In this article, high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles.

TL;DR: It was demonstrated that inexpensive high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles.

TL;DR: In this article, the authors describe the properties and properties of carbon nanotube yarns, ribbons, and sheets, including extreme toughness, resistance to failure at knots, high electrical and thermal conductivities, high absorption of energy that occurs reversibly, up to 13% strain-to-failure compared with other fibers with similar toughness, retention of strength even when heated in air at 450°C for one hour, and very high radiation and UV resistance, even when irradiated in air.

TL;DR: Guest-filled, twist-spun carbon nanotube yarns are designed as electrolyte-free muscles that provide fast, high-force, large-stroke torsional and tensile actuation and can solve the problems of speed and lifetime.
