Self-healing circuits guarantee zero circuit failure

There are times when our electronics go berserk and fail due to a circuit failure which is impossible to fix. If one minute circuit fails in a chip, then the entire chip fails and the electrical gadget becomes useless and has to be disposed. The circuit failures and the redundant electronics have also led to the filling of our landfills which is detrimental for the environment. However, there is good news now as a team of engineers from the University of Illinois have developed a self-healing mechanism in which the circuit could actually fix itself, without destroying the entire system!

Self-healing electronics could work longer and reduce waste

The team is headed by professor Scott White who specializes in aerospace engineering and Nancy Sottos who is a materials science and engineering professor. They have developed an innovative system in which a cracked circuit can repair itself in less than a second and restore the electric conductivity to rest of the device.

At a large scale, sophisticated technology is being used for developing devices and that is why the chips have denser compounds that lead to a higher probability of failure at any point. Circuit failures are so delicate to detect that you cannot figure out source of the same. The team of engineers have placed micro capsules on the circuit that opens up and releases a liquid metal that actually sets in the gaps of the circuit and restores the electrical conductivity to normalcy.

This self healing system would be a boon in the field of aeronautics, diagnostics, aircraft, spacecraft and many other fields wherein safety and long life of the device is very critical.
