Stiffer than steel!!!

Carbon Nanotube Aerogel Muscles can be stiffer than steel by weight despite being as light as air, and elasticity comparable to a rubber as reported in the latest issue of Science magazine. Here are two articles, one is the perspective and another is the research article! Quite amazing!

One Response to Stiffer than steel!!!

    this is a video showing how the CNT aerogel expands when a voltage is applied across it.
    Repulsive forces between the nanotubes rapidly triple the material’s width, causing it to expand at 37 000 percent per second. That’s 10 times as far and 1000 times as fast as natural muscle can move, and the material does so while generating 30 times as much force as a natural muscle.
