Chips that repair themselves alone

Researchers at the University of Illinois (USA) have developed a circuit capable of automatically returning the electrical conductivity to parts of it that have lost some breakage. At present, a failure of this nature requires changing the chip, and are becoming more common mistakes due to increased density that manufacture these devices.
The invention involves placing a liquid metal microcapsules, about 10 microns in diameter, above the chip areas that perform electrical conduction. If a break in the conductive material slides the liquid metal in the gap in microseconds. In tests 90 percent of chips of this mechanism is gifted recovering autorrepararon 99 percent of the original conductivity.
The main application could be in vehicles or military or space where the electronics can not be replaced or repaired.
A great advantage of this system is that it is located and autonomous. In other words, the microcapsules are broken only in places where there is a problem and they do not need human supervision.
