The development of artificial muscles, scientists are already not the first year. The creation of a complete muscle will make it possible to produce high-tech prostheses for people with disabilities, greatly improving their quality of life. New lightweight and durable material for such purposes as recently invented by scientists from MISIS.
The main obstacle for the transplant of the artificial muscle man is that most of the materials used in a muscles, are highly toxic. However, the Russian researchers managed to conduct a series of experiments that proved that the basis of the artificial muscle can be a substance on the basis of polyethylene with extended chain molecules. Scientists from nust “MISIS” polyethylene reinforced with carbon nanotubes, whereby the wear resistance was increased in two times, the service life of the material can reach 15 years.
The resulting material can be used not only as raw material for the production of artificial muscles, as when it is cooled it contracts, and expands when warm, mimicking muscle contraction. But in the manufacture of bones. Experts nust “MISIS” created a replacement bone — the outer layer is solid, and the interior is porous, which simulates the biological structure. It was obtained by combining the methods of solid-phase mixing and timepressure, and to create a been used supercritical fluid. Under certain conditions it is transformed from water to gas and evaporates, leaving pores, the content of which the material is 80%. As noted by candidate of physico-mathematical Sciences, researcher of the research center of composite materials nust “MISIS” Fedor Senates,

“This material is perfectly cut, which is very profitable for surgeons. He also possesses shape memory effect, that is, if you squeeze it, and then put in the right place, he “straightened”. So you can significantly reduce the time and complexity of the operation”.
