In today's complex chip is enough to break down just one touch - and the entire device can be a total loss of performance. If only those contacts do not ...
The more complex and miniature chips become, the closer manufacturers place their components, the great challenges they face. The device is sensitive to temperature fluctuations, quickly degrades over time... and the failure of just one piece of a single conductor can result in failure of the entire scheme. Repair of tiny circuits - a thankless task, and often impossible, and usually they have to be replaced by a new.
If a household has to live with it - and we just have to regularly update your ... This, of course, talking about applications such as military, aerospace, transportation, - those where you just can not leave room for mistakes and failure. As a result, electronic systems are becoming extremely complicated, with the duplication of all critical components, or with built-in diagnostics.
To simplify this situation promises to the work of American researchers, carried out under the direction of Scott White (Scott White) and Nancy Sottos (Nancy Sottos). The authors suggested that the chip, which alone restores the functionality of damaged wires - and does it in a few moments.
To demonstrate his idea, scientists have taken a simple guide on the gold substrate and sprayed him in the tiny 10- micron capsules, while containing the liquid metal. When you see a small gap in the conductor under the influence of temperature, the capsule were destroyed, and the metal filling the gap. During the current is restored within milliseconds. After the first test in 90% of the electrical conductivity of samples recovered by the amount of 99 % of the initial.
In each of these ... Recovering chip is ... ...
Now, of course, scientists are busy improving the method and the search for other ways to use their ... Ideally, they want to integrate them into the modern system of electrochemical cells and batteries, in order to improve their performance and service life.
