Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Voltage Increases Observed in Closely Packed Nanowires

Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents — including batteries and certain solar arrays — may need to make allowances for such surprise boosts.
