A group of American and Canadian engineers,Chemists and biologists from the University of Connecticut and the University of Toronto have developed a new type of sensor, giving artificial skin the ability to feel pressure, vibrations and even magnetic fields. This technology will help recover from burn victims and people with other injuries of the dermis. The invention is reported in detail in the journal Advanced Materials.
The new sensor consists of a flexible hollow siliconetube wrapped with copper wire and filled with iron oxide particles. As the iron nanoparticles move inside the tube, they create an electrical discharge that is transmitted to the copper wire. When pressure is applied to the tube, the current changes.
"The type of artificial leather that we developedcan be called electronic skin. This is a new kind of electronics with flexibility, stretching properties and unique sensory capabilities that mimic human skin, ”said Islam Mosa, a postdoctoral student at Connecticut University.
In addition to being like human skinperceive changes in the environment; electronic skin is able to sense even fluctuations in a magnetic field and vibrations of sound waves. According to the co-author of the work of Abdelsalam Ahmed from the University of Toronto, the researchers set themselves the task of developing artificial skin, whose sensory capabilities go beyond the human.
“Great motivation for us in developing thisThe sensor for electronic skin was the desire to expand the capabilities of this technology to superhuman abilities. We have shown that electronic skin can serve as an effective hazard sensor, ”says Ahmed.
The developers believe that their invention will findinterest among manufacturers of electronic security systems, developers of robots for rescue operations, as well as new generation devices for remote monitoring of health status. In the future, the creators of the sensor plan to develop a flatter prototype that can more naturally integrate into the artificial skin and not stand out against its background. In addition, scientists plan to make e-skin completely biocompatible.
The authors of the project note that the costproduction of one such sensor is currently less than $ 5. Scientists have patented their development and plan to enter the market with it in the next couple of years.
