Good news for the burn victims or smooth and durable skin lover. A new innovation from MIT (Massachusetts Institute of Technology) has successfully developed artificial skin and nerves are normal physiological functioning.
MIT research team, not only successfully developed the artificial skin, but also ensures that artificial tissues function like a normal skin, in which there are blood vessels and nerves. This innovation is expected to help burn victims, or anyone who needs a new skin tissues.

This innovation begins with the success of developing a method to bind the gelatin (hydrogel) with an elastic polymer material (elastomer). Both are basic materials to make artificial skin cells, neural tissues, and long lasting contact lenses.
To note, if we make jelly (hydrogel), within a certain period, it will evaporate, leaving the shrinking masses, harden and shrivel, with a form that is not attractive. The same applies to the hydrogel. Due mostly made of water, the hydrogel will expand when it absorbs water and shrinks when it dries and wrinkles.
Now, MIT researchers find ways to prevent the effects of dehydration of the hydrogel. They use a special technique that can cause us to be able to make the long lasting contact lenses, elastic microfluidic devices, flexible bio-electronic devices, and even artificial skin.
The team leader named Xuanhe Zhao of the Department of Mechanical Engineering of MIT devised a method for binding hydrogel and elastic polymer (elastomer) such as rubber and waterproof silicone. They found, among the hydrogel with a thin elastomer layers provided retaining water trap which makes hydrogel remains moist, flexible, and powerful. The results are published in the journal Nature Communications on July 2016.
Imitating Human Skin
Zhao said the team was inspired by the design of the human skin, which has bonded the outer epidermis and dermis layers protect. Epidermal layer acts as a shield that protects the dermis, nerves, capillaries, as well as the muscles and organs of the drying effect.
"We hope this study will pave the way for the manufacture of synthetic skin, blood vessels and artificial neural tissues so that it can create bionic robot capable of operating as an intelligent living beings who have skin, organ maun biological tissues in general," said Zhao. *** [EKA | FROM VARIOUS SOURCES | MIT NEWS | INSIGHT]
