New electronic skin will allow you to control real and virtual objects

Artificial skin has largely begins «bypassing» current
Thanks to the joint work of scientists from Germany and Austria, was the first to create artificial skin that is able to handle simultaneously tactile and non-tactile signals. Previous attempts to combine these features in one device were not successful. However, with the new development, humanity has become a step closer to creating a functional artificial skin.
How does faux leather?
— it is the largest organ of our body. However, he and one of the most complex. The skin is not only able to distinguish between the different incentives, but at a fraction of a second, but can classify these signals. To distinguish cold from hot, to feel the texture of objects, learn properties (soft, sharp, prickly), transfer pain, and so on.
According to the publication , the Research team, led by Dr. Denis Markov from the Center.Helmholtz and Martin Kaltenbrunner from Linz University, has managed to create the electronic equivalent of human skin is almost completely identical characteristics. According to scientists, the new sensor would greatly simplify the interaction between people and machines.
For Example, applications in virtual reality are becoming increasingly complex. Therefore, we need devices that can handle and pass multiple options of sensations. Now the existing devices transmit a maximum, two types of signals. — scientists say
Modern systems work or only registering physical touch, or tracking objects in a contactless manner (using cameras). Both were United for the first time on the sensor, which was called «magnetic microelectromechanical system» (m-MEMS). In our channel in the Telegram we regularly inform about the latest developments like that. So if you are interested in the world of high technology — !
Our sensor processes the electric from multiple sources at once. Thus, it can differentiate the origin of the incentives in real time and transmit them for processing.
M-MEMS astrovan on a thin polymer film, reinforced with a layer of polydimethylsiloxane. Inside is a circular cavity, where the magnet with a pyramidal tip. The cone protrudes above the surface of the sensor is something like nerve endings. The pyramid is supplied to the electrodes can detect heat, cold and other sensations, and due to the fact that the cone protrudes above the surface and the bottom is held by the magnet, when pressed, he can recognize the hardness and density of the object. The sensor according to scientists, it is very easy to place, for example, on the tip of your finger.
This sensor can be used as a control, both physical and virtual objects. For this, a series of experiments. On a glass plate, behind which was located a powerful magnet, physicists have projected virtual buttons. Magnet operated lighting system in the room, and button — temperature. With the help of "electronic skin" they first turned the light on, simply by swiping the sensor near the magnet, and then as soon as the finger touched the glass, the sensor of the m-MEMS are automatically switched to tactile interaction. Using different pressure, it was possible to adjust the temperature of the surrounding air.
This may, according to the creators, to find application in various fields. From helping people suffering from skin lesions (for example, after severe burns and wounds) and to work in virtual-reality environments. For example, surgeons can use the sensors to operate the medical equipment, which takes place in the most sterile environment. Thus, physically the doctors will not touch it during the procedure, which will reduce the risk of infection.
