Springy Nanotubes Could Make Artificial Muscles 70

moon_monkey writes "Scientists have discovered that carbon nanotubes have remarkable springy properties, which could make them ideal for use in artificial muscles. Currently, electroactive polymers are most commonly used to make artificial muscles, but these lack mechanical robustness. Researchers at Rensselaer Polytechnic Institute tested the nanotubes by repeatedly squashing them between metal plates. The work is reported in Nature Nanotechnology."
