US Army develops "magnetic nerves" for combat vehicles

It is not very pleasant to find your car one day in the yard of a house or somewhere in a parking lot with numerous dents, without having the slightest idea about their origin. Now imagine that the car will feel the "pain" inflicted on it and immediately inform its owner about it.

Scientists at Clemson University commissioned by the US Army are developing systems that can be roughly called "nerves" for machines.

The basis of these "nerves" is a magnetostrictive material that responds to changes in the magnetic field or physical impact. It is placed between several layers of composite materials from which the vehicle is made. The system will react to unusual mechanical stresses, “feel” the appearance of cracks and dents, and transmit the received information to a computer for processing.

The researchers believe that it is much better to integrate the damage sensors into the body of the car than to install them separately later. Smart materials also make it easier to repair and maintain military vehicles. The fact is that the wear and tear of equipment is not always visible, but, nevertheless, after a certain time, individual parts are replaced, regardless of their condition. The sensors will allow you to accurately determine the degree of their wear.

According to scientists, they have already received $ 1 million from the research division of the Pentagon, the US Army Research Lab, to develop the material, which can take from 10 to 20 years.
