The electronic skin, sensitive to even a breath of wind

Scientists from all over the world already not the first year working on the creation of “synthetic” or e-skin, the application of which can be found not only in robotics but also in the creation of prostheses, ultra-sensitive sensors and flexible electronics. Recently we wrote you about the fact that such sensors in the form of a spray was created by experts from South Korea, but it is now known that their colleagues from the Chinese Academy of Sciences have developed the most authentic electronic skin. So sensitive that it can detect even a drop of water and the wind.

About a very interesting development writes the online edition of Science Robotics. Electronic skin gives the ability to register the slightest changes in pressure through the hollow polymer membrane that is coated with magnetic sensors. In the upper part of this “sandwich” is built in a small magnetized beads. The pressure on this e-skin membrane pressed, and the beads closer to the sensor. Since both elements are magnetized creates resistance, which is logged and sent to the chip. After that, the chip converts the data into pulses, on the basis of which a conclusion about the intensity of this pressure, which gives eventual ideas of what is “felt” an electronic skin.

Fragments of faux leather with built-in magnetic sensors

Moreover, the development of conventional models of Chinese researchers did not stop there and created an artificial finger, which was covered with the electronic skin. This finger was connected to an artificial arm and ran a series of tests. According to experts, during the experiments, electronic skin could catch even a slight pressure. The device recorded the change in wind speed, the difference in the size of the droplets dripping on her, and even ants running over the surface.

The experts themselves believe that their development will be useful primarily in the field of robotics, after all, covering her robotic mechanisms, “to give them the opportunity to feel” in order to be able to perform more complex, precise actions. Thus, to create a full faux leather left only “teach” it to respond to changes in temperature.
