Self-repairing, reconfigurable electronic circuits take a step closer to reality

By - January 31, 2015 1 Picture
If electronic circuits could automatically reconfigure their internal conductive pathways as required, microchips could function as many different circuits on the one device. If many of these devices were then incorporated into larger pieces of equipment, such as robots, it is possible that self-sufficient, self-sustaining machines could change to suit their environment or even reconfigure broken or damaged pathways to repair themselves. Promising applications like these – and more – could one day be made possible if technology resulting from recent research into atomic manipulation at École polytechnique fédérale de Lausanne (EPFL) comes to fruition.

Regenerating plastic is better on the "hole"

By - May 11, 2014 16 Pictures
Dropping your mobile phone can ruin your whole day as you look down at the spiderweb of cracks surrounding a small hole in the once-pristine plastic case. Now imagine watching as those cracks and that hole seal up by themselves, leaving behind a completely healed case. That may sound like science fiction, but it may not be for long with a team of researchers at the University of Illinois having developed a new system that doesn't just repair minor cracks in plastic, but regenerates to heal large holes.

Vascular self-healing system allows composite materials to repair multiple times

By - April 16, 2014 1 Picture
We've seen numerous examples of self-healing polymers that allow materials to repair themselves after being damaged. One of the more common approaches involves the use of embedded microcapsules that release a healing agent when damaged. Researchers have expanded on this idea to develop a new technique that brings self-healing capabilities to fiber-reinforced composite materials, like those used in airplanes and automobiles.

Self-healing polymer restores itself in minutes

By - April 14, 2014 1 Picture
Researchers at Germany's Karlsruhe Institute of Technology (KIT) have developed a self-healing polymer that can mend itself and fully restore its mechanical properties in just a few minutes when heated at low temperatures. The material could be used to create self-repairing sealants, scratch-resistant paints, and more reliable fiber-reinforced plastic components. Read More

Scientists watch bioengineered self-healing muscle tissue grow within a mouse

By - April 2, 2014 3 Pictures
The living skeletal muscle tissue grown by Duke University researchers is 10 times stronger than any previously bioengineered muscles. Not only does it contract as strongly and as rapidly as the real thing but it is also capable of self-healing, both in the lab and after implantation into an animal. This has been proven beyond any doubt through a novel approach that involves peeking at the growing muscle tissue through a glass window in the back of a living mouse. Read More

Bacteria combined with gold to produce "living material"

Scientists at MIT are developing hybrid materials that are a cross between living bacterial cells and non-living components such as gold nanoparticles or quantum dots. The resulting "living materials" are able to respond to their environment like regular living cells, while also doing things like conducting electricity or emitting light. Read More

Military vehicles could soon feature self-healing paint

By - March 19, 2014 1 Picture
According to the US Department of Defense, corrosion costs the Navy approximately US$7 billion every year. That's certainly an incentive for developing a method of keeping military vehicles from rusting. Now, researchers from the Office of Naval Research and The Johns Hopkins University Applied Physics Laboratory may be onto something. They're looking into the use a powder that could allow scratched or chipped paint to "heal like human skin." Read More
