Physicists have created a synthetic leather with the ability to regenerate

In the U.S., physicists developed superflexible material which is self-heal scratches and cuts, and can also recognize touch.

According to the creators, the material can be used as a basis for synthetic leather.

"Prior to our work, it was difficult to imagine that we can create such a flexible and well-conductive material that can heal cuts and scrapes. Fresh cut "healed" in this skin for a few seconds. Even human skin heals in a few days. In general, I think it's pretty cool ", — the representative of the school of engineering at Stanford University (USA).

A group of physicists led Chzhenan Bao of Stanford University for several years trying to reproduce the key features of the skin — flexibility, strength, sensitivity and the ability to heal injuries — in the artificial material.

In the new work the authors have decided to "teach" the most complex artificial skin her alive property progenitor — the ability to self-medicate.

Bao and colleagues have solved these problems by using two key components — a special hydrocarbon polymer and nano-powders of nickel. According to scientists, the hydrocarbon chains have several useful properties — they are very flexible and mobile in nature, the need for self-skin, and good conduct electricity.

Scientists have produced a thin sheet of a mixture of polymer and nickel nanoparticles and investigated how it will react to the cuts.

The study found that the material can self heal wounds almost within seconds after shrinking its sides. Wound completely heals after 30 chekund.

Bao and her colleagues believe that the new version of synthetic leather will "feel" even the small amount of pressure, which occurs when a hand shake.

The researchers believe that their invention will attract the attention of doctors and other scientists who develop prosthetic legs and arms in the near future.

According to them, the scope of this material is not limited to — a transparent and stretch version of the skin can be adapted to work as a sensor for the screens of mobile devices and other equipment.

Recall that in July of this year, engineers have created a touch sensitive sensor, which is able to distinguish between pressure, shear and torsion.
