Watch this iPhone screen protector heal scratches within a second

The folks who came up with the self-healing iPhone case is now back with something a lot more impressive. Innerexile's earlier technology could repair light scratches within about half a minute (given the right temperature, that is), but the latest...

Caltech self-healing chips can recover from laser blasts, save power while healthy

Caltech selfhealing chips recover from laser destruction, save power in the process

While many scientists have heard the call for self-healing electronics, their previous projects have usually had just a limited capacity to come back from the brink. Caltech has developed an integrated circuit that could take much more of a bruising. Its prototype power amplifier chip has a dedicated circuit and sensors that can change actuators in microseconds if there's damage, re-optimizing the connections on the spot. And the chip can take a lot of that damage -- 76 examples in a penny-sized cluster endured multiple laser strikes in tests (like the one above) while still ticking. The self-healing even helps while everything is in tip-top shape, as it can cut power use by watching for the usual hiccups in load and voltage. So long as Caltech can develop the technology beyond its currently expected niches of communication and imaging, many of our computing devices could eventually take a few bumps and scrapes on the inside, not just their rugged exteriors.

Graphene heals itself, powers our dreams and nightmares

Graphene heals itself

Slowly, but surely graphene is pushing our technological hopes, dreams and, yes, nightmares towards reality. The stuff is capable of extending battery life, generating electricity, powering high-speed data connections and super computer-worthy CPUs. It's water proof, stretchy, bendy and apparently self healing. (This space reserved for T-1000 reference.) Researchers at the University of Manchester discovered that, if you put a hole in a sheet of graphene, it simply stitches itself back together. This is thanks to carbon's tendency to latch on to other atoms, including its own, which can make the futuristic material difficult to work with, but gives it this highly unique quality. Thankfully, we're no where near self-healing robots. But, the discovery could lead to a simple method for molding it into almost any shape. Once pierced, the form of the mend is determined by the type of molecules introduced -- pure carbon simply regrows the perfect honeycomb structure, while a few foreign atoms can lead to "defects." Of course, if they're intentional and predictable, defects merely become "features." For more check out the source link.
