New e-skin is sensitive to touch and self-healing

The human skin, with all its frailties, turns out to be difficult to recreate, let alone improve on. The main challenge: It manages to be both self-healing and sensitive to the touch, enabling it to send vital information to the brain about temperature and pressure.

But chemists and engineers at Stanford say they are one step closer to developing an electronic skin that has both these properties, and they report this week in the journal Nature Nanotechnology that it could help lead to smarter prosthetics and more resilient, self-repairing electronics.

Their central task was to find a self-healing material (a … Read more

New breed of plastic bleeds, heals itself

Researchers at the University of Southern Mississippi have developed a new kind of self-repairing plastic that could lead to impenetrable cell phones, laptops, and cars -- or the next Terminator.

Team lead professor Marek W. Urban presented the results of the research at the National Meeting & Exposition of the American Chemical Society in San Diego this week, revealing a type of plastic that mimics human skin.

Though self-healing plastic isn't a new concept, Urban says the benefit of his team's plastic is its warning system and ability to repair itself over and over again. … Read more

These tires repair themselves

Self-driving vehicles, self-parking cars, self-repairing paint ... and now self-healing tires? Michelin says it has accomplished this feat by using manufacturing techniques that mold the tread of its XDA5 in three dimensions. What that means to us commuting plebs is that the tire features a tread that somehow regenerates itself as it wears off. It sort of acts like an onion: As the tire wears, the tread reveals new grooves and tread blocks within. Once again, technology aping nature.

Unfortunately, this isn't multi-layered, so you won't be getting treads that last forever. Just a touted 30 percent extension in … Read more
