Magnitoreception – it is the sense that allows bacteria, insects, birds and sharks to detect magnetic fields for orientation and navigation. However, humans are generally unable to perceive magnetic fields.
That is, undoubtedly, magnetic fields have an impact on the physiological processes of a person, but he does not perceive similar other information perceived by the five senses.
Dr. Denis Makarov and his team have developed a so-called electronic skin with a magnetically sensitive system, which activates the wearer's sixth sense, which allows him to perceive the presence of static or dynamic magnetic fields. This invention, less than two micrometers thick and weighing three grams per square meter, can even float on a soap bubble.
The new magnetic sensors are able to withstand strong bending with a radius of less than three micrometers, and it can also be crumpled like a sheet of paper. In this case, the performance of the sensor is not reduced. On an elastic base, presented in the form of a rubber band, it can be stretched by more than 270% and for 1000 cycles without weakening. Such characteristics are conveyed by the magnetoelectronic element by their ultra-thin, ultra-flexible and extremely strong polymer substrates.
"We have demonstrated a dermal non-contact human-machine interaction platform, a sensory device for movement and movement that can be used in soft-bodied robots, functional medical implants, and simply for orientation and manipulation purposes", – scientists explained.
Work on the creation of a magnetic sensor was carried out at the Institute for the Study of Solids and Materials (IFW Dresden), as well as at the Chemnitz Technical University (YU Chemnitz) in close cooperation of German scientists with Japanese colleagues from the University of Tokyo and Osaka.
