Snake Rovers on Mars

Annnnd hello and welcome to this week in engineering brought to you by engineering.com spider silk muscles spider silk is stronger by weight than steel and is also stretchable while carbon nanotubes are electrical conductors that are also stretchable now Florida State University physicist even Steven and colleagues coated strands of spider silk with carbon nanotubes and found the resulting material has a lifting strength about 50 times stronger than muscle. The best adhesive between the silken nanotubes turned out to be drops of water put under pressure from to teflon plates. The coded so could still stretch up to 50 percent of its original length. To demonstrate possible applications the researchers also made a heart beat sensor which measured the change in electrical resistance with the stretching of the code silk strands ...
