The effectiveness of the material is 15 times higher than natural fabrics
A group of researchers from the University of Illinois in the United States had established a record of payload material for artificial muscles. Muscle thread weight 1.6 grams can lift a weight of 1.9 kilograms, writes the Chronicle.info with reference for Today.
Still record the multiplicity of lifted weight was a thousand times exceeding its own weight “muscle”. The invention of illinoize able to lift the load, which in 12.6 thousand times its own weight.
The resulting material is durable, can withstand 60 MPa mechanical pressure and can be extended by 25 percent. Its efficiency is 15 times higher than the natural fabrics.
The basis of artificial muscles are carbon fiber, several thousand of which is twisted into a bun. Polymer impregnated bundle of fibers is twisted and subjected to heat treatment for days, after which it twist the spiral and get a strong spring, capable of lifting a lot of weight.
