Super-Strong Nanotech Yarn Could Soon Power Robots & Micromotors
New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power than the same size natural muscle. Dr. Ray Baughman of the University of Texas at Dallas' NanoTech Institute explains the operation of a new type of super-strong carbon nanotube yarn, which could one day help power robots, make intelligent textiles, and more. The researchers demonstrated a contractile power density of 4.2 kW/kg, which is four times the power-to-weight ratio of common internal combustion engines.
