Scientists close to creating eternal electronics March 13, 2013
Scientists are actively working to improve the immunity of electronic devices. California Institute of Technology ( Caltech ) demonstrated a chip-resistant not only to the effects of high-power laser beam, but also to more general problems, such as aging, voltage fluctuations, temperature changes and load mismatch.
This approach is not new, although it is more flexible and efficient. The chips are equipped with sensors measuring temperature, power, current and voltage, which transmit data to a central processor (ASIC). A specially designed chip application monitors the system’s performance and adjusts the operation of its operational components.
Chip quickly responds to any failures, while improving system performance. This is despite the fact that the recovery of additional energy is required. In fact, power amplifiers consume almost twice less energy than an equivalent system without self-healing.
The photo below shows how the electronic chip to reset themselves after it was cut with a laser.

Ability to continue to operate in all conditions suggests that the self-healing chips can be used in virtually all electronic systems.
“Granting immunity integrated systems opens up a host of opportunities. This completely changes our understanding of how the chips. They learned how to find and fix damage on their own, without human intervention. We are close to creating a perpetual electronic devices ”
– Professor of Electrical Engineering at Caltech Hadzhimiri Ali (Ali Hajimiri).
This work, like the rest of the most interesting research was funded by the Office of Advanced Research Projects of the Ministry of Defence of the United States (DARPA) and the Laboratory of the U.S. Air Force (Air Force Research Laboratory).
