article a fundamentally new method for creating artificial muscles on the basis of the usual fishing line and other similar polymer filaments, without using expensive or exotic materials such as carbon nanotubes,
vanadium dioxide or metal memory alloys. Moreover, their method of manufacture is trivial and entirely available at home - a monofilament twisted under load until it will roll in a spiral, and then heated. Upon heating coil is reduced by developing a sufficiently large force during the cooling is extended to its original dimensions.
