Scientists from northeastern University in China have developed a light-sensitive artificial skin that is able to operate due to the energy fluctuations during walking or when blinking of the eyes, and directly connect to the brain.
The device is made from polymer composite material. It is applied in several layers on a copper substrate and covered with a layer of conductive polymer of polypyrrole with holes.
This part of the skin can conduct electric current, which changes during irradiation and also serves as an energy source and a photosensitive detector.
With the brain’s “skin” is attached using a special electrode. Thus, the device will help to distinguish between images of people with damaged retinas.
To “leather” started to work, fairly small mechanical movements like blinking.
The efficiency of the device so far tested only on mice. For people faux leather necessary improvements.
