MIT Engineers found a way to make Artificial Muscle using ordinary Nylon Fibre | QPT


MIT engineers have discovered a simple and inexpensive method for fabricating artificial muscle fibers using ordinary nylon fibre. Pulling inspiration from nature is not a new concept for engineers, specifically the attempt to mimic or replicate the intricacies of muscles, how they move and bend ,extend, contract and so on, is something researchers have been interested in learning more about for some time now artificial muscles can have many applications, from robotics to some components in the automobile and aviation industries but they are currently very expensive and limited in their capabilities however now a group of MIT researchers have come up with one of the simplest and lowest-cost systems yet in which material reproduces some of the bending motions that natural muscle tissues perform regularly. The key ingredient? nylon fiber. It turns out some polymer fiber materials including a special type of nylon have an unusual property when heated they shrink in length but expand in diameter the researchers found that by modifying the shape of the fiber and then selectively heating it on one side they can force the fiber to bend. By heating specific areas of the fiber and sequence they found they can produce more complex movements for example in their lab tests the team used this technique to get the fibers to move in circles and then in figure eights various heat sources can be used on the fibers including electric resistance heating chemical reactions or a laser beam that shines on the filament someday the researchers suggest this kind of system can be used to produce a variety of biomedical devices robotic grippers or machine components
