A new type of artificial electronic skin allows you to feel touches

Modern technologies already allow us to recreate limbs controlled by the power of thought, and even partially restore sight and hearing to people who for one reason or another are deprived of them. However, something to this day remained inaccessible to modern science: the development of artificial leather. And we are not talking about the grown living tissues (this is successfully handled by transplantologists), namely, the creation of an electronic analogue of the skin, which would have all its properties. And a group of experts from Stanford University for the first time in history managed to design the most real "electronic" skin.

According to the publication Nature, the development engineer Zhenan Bao, who for several years has been designing various elastic and sensitive electronic materials, which would allow to feel the touch, heads the development. Ms. Bao managed to create an elastic polymer circuit with a built-in touch sensor. Such material, among other things, can also act as a touch screen, that is, it is used not only to create artificial leather, but also in the production of flexible electronics.

The new invention consists of several layers of polymers. The main layer is responsible for flexibility and elasticity, while others are complex electronic circuits. These layers are separated by a third kind of polymers – dielectrics, insulating materials and preventing undesirable interaction of the layers with each other and with the environment. In 1 square centimeter of "electronic skin" is concluded more than 6000 different sensors and devices, which together work on the same principle as the nerve endings.

As scientists assure, already now the existing prototype can be stretched in 2 times in comparison with the existing size without loss of properties. In addition, scientists have come very close to creating a process for the mass production of such skin. Having created whole sheets of this material, one can not only return a lost sensitivity to a person, but also find a lot of applications in the creation of flexible electronics, medical sensors, sensors and even robots of a completely new type.
