Robots could flex muscles that are stronger than steel - tech - 19 March 2009 - New Scientist
Scientists have developed a material made of ribbons of nanotubes that expand up to 220% when a voltage is applied, then return to normal when the voltage is removed, all within a few milliseconds. The material is apparently stronger than steel and stiffer than diamond, and operates over a range of temperatures extending from liquid nitrogen to above the melting point of iron. The downfall is that the material, made from an aerogel, is 1000 times less dense than human muscle. As a result, large volumes of the material are needed o achieve a strength approaching that of the human arm.
