Efficient, Absorption-Powered Artificial Muscles Based on Carbon Nanotube Hybrid Yarns

Efficient, Absorption-Powered Artificial Muscles Based on Carbon Nanotube Hybrid Yarns

A new type of absorption‐powered artificial muscle provides high performance without needing a temperature change. These muscles, comprising coiled carbon nanotube fibers infiltrated with silicone rubber, can contract up to 50% to generate up to 1.2 kJ kg−1. The drive mechanism for actuation is the...

Zusammenfassung:A new type of absorption‐powered artificial muscle provides high performance without needing a temperature change. These muscles, comprising coiled carbon nanotube fibers infiltrated with silicone rubber, can contract up to 50% to generate up to 1.2 kJ kg−1. The drive mechanism for actuation is the rubber swelling during exposure to a nonpolar solvent. Theoretical energy efficiency conversion can be as high as 16%.
