Chips that can repair themselves – Part 1

They are based on microcapsules of liquid metal which overcome any cracks of integrated circuits, almost immediately.

When a tiny circuit, integrated on a chip, breaks or fails, the entire chip, and even the entire device containing the chip is ruined. What if the circuit could manage to repair itself, so fast that no one could even notice if it’s broken?

Scientists at the University of Illinois, United States, have managed to develop a technique that achieves just that: the system detects any failure in an integrated circuit and repairs it on the go, in a time interval less than the blink of an eye. And
all this occurs without the users noticing. The breakthrough could help prolong the life of electronic devices and improved batteries.

A team of researchers from the University of Illinois , United States, has been applied to power systems expertise in polymer self-healing, to develop a technology that could extend the life of electronic devices and batteries. In particular, engineers have
developed a self-healing system that restores the electrical conductivity of a broken circuit in less time than blink of an eye.

Led by engineer aerospace Scott White, and engineer specializing in materials science, Nancy Sottos, researchers have published details of its development in the journal Advanced Materials.

Simple systems Statements by Jaffrey Moore, another one of the authors of the concept and its advances, contained in a statement from the University of Illinois, this new technology will simplify electronic systems. Thanks to her, instead of having to make
too much for replacements or having to make diagnostic sensors to control the operation of the circuits, they can fix the problems by themselves, says Moore.

As electronic devices evolve to perform increasingly sophisticated tasks, the density of the chips is increasing. This higher density leads to many problems of reliability, and failures as those caused by fluctuating temperatures derived from the operation
itself or fatigue of the devices. Any problem at any point of the circuits can kill the whole set.
