Spider silk could be used as robotic muscle

by Massachusetts Institute of Technology, Phys.org

Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.

The resilient fibers, the team discovered, respond very strongly to changes in humidity. Above a certain level of relative humidity in the air, they suddenly contract and twist, exerting enough force to potentially be competitive with other materials being explored as actuators—devices that move to perform some activity such as controlling a valve.

Spinning spider silk is now possible

by Swedish University of Agricultural Sciences, Science Daily

Being able to produce artificial spider silk has long been a dream of many scientists, but all attempts have until now involved harsh chemicals and have resulted in fibers of limited use. Now, a team of researchers from the Swedish University of Agricultural Sciences and Karolinska Institutet has, step by step, developed a method that works. Today they report that they can produce kilometer long threads that for the first time resemble real spider silk.
