Scientists have discovered a new way to make artificial muscles from doing something every angler has done at least once in his life: twisting fishing line.
This video from the University of Texas at Dallas shows how tightly wound fishing line reacts like a muscle when exposed to heat. The line contracts when heated; relaxes when cooled. This discovery could be the foundation for material used in prosthetic limbs, implanted medical devices, wearable clothing, and window blinds that react to changing temperatures.
According to the researchers, the muscle created from fishing line is 100 times stronger than any known living muscle — human or animal. And it is far stronger and cheaper (about $5 per kilogram) than currently used materials like muscle strand substitutes, carbon nanotube yarns, and metal wires.
