Springy Nanotubes Could Make Artificial Muscles

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."

    A Nano-Tube article right next to a Ted Steven's article.

  2. Why are we working for Artificial Muscles? by Pionus · · Score: 4, Funny

    People who would need Artificial Muscles are a small minority. We need to improve the lives of the majority people. Imagine the joy that a enhanced nanotube superball or silly putty could bring to the world!

      Yes, but that is just you for one.

    If your erections are remarkably springy, I strongly advise you to stop posting and go see a doctor. You two have a lot to discuss.

  4. Artificial Muscles better than normal? by Apocalypse111 · · Score: 3, Funny

    With normal muscle tissue, strength increases proportional to cross-sectional area, while the weight of both the muscle itself and the object being lifted increases proportional to volume * density. Thus, weight can easily outstrip the ability of a muscle to lift it. This is one of the determining factors in why we do not see giant monsters, as they would be unable to lift their own bodies.

    So, were this new artificial muscle to be developed, would it be constrained by the cross-sectional area rule that normal muscles adhere to? Feasibility and practicality aside, could this be one of the major stepping stones toward having my own giant robot?

    There is no mod option "-1: Disagree" for a reason. "Overrated" is not an acceptable substitute. Post something instead.
