Nylon filament when heated able to shrink in length and increase in diameter.

Scientists from mit have created artificial muscles made of nylon fibers and is able to bend, reported, citing .

About their development, the researchers reported in an article published in the journal Advanced Materials.Nylon filament when heated able to shrink in length and increase in diameter. To get them to bend normally required pulleys and coils, but they make the design too complicated. However, scientists have been able to achieve the desired effect by heating only one side of the filament. The nylon was processed so that the cross section of the fiber had the shape of a rectangle or square.Artificial muscles can be used in clothing, footwear, as well as in catheters and other medical devices.
