A team of researchers and engineers at California Institute of Technology (Caltech) has developed ‘self-healing’ chips that would heal themselves within a few microseconds and recover from faults that may range from low battery power to complete transistor failure! Pretty cool stuff and you can read the entire research paper [PDF] here.
The engineers demonstrated the self-healing capabilities through tiny amplifiers; a total of 76 of them alongside everything else that is needed to carry out self-healing – all of it able to fit on a penny. The team went to the extremes in testing if their work actually yielded results for which they damaged the amplifiers at several places by zapping them with high-power lasers. Within a second, the chips were able to develop work-around thereby healing themselves.
