Springy Nanotubes Could Make Artificial Muscles

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 — via Slashdot
