Self-healing

Although you are fairly unlikely to start zapping your gadgets with high-power lasers any time soon, scientists are already hard at work trying to make electronics immune to such cruelty. In another in a series of self-healing electronics breakthroughs, a team of scientists from the California Institute of Technology (Caltech) demonstrated chips capable of dealing not only with laser-inflicted physical damage but also with far more common ailments such as aging, power fluctuations, changes in temperature or load mismatch.  Read More

NC State's self-healing elastic electrical wire

Last month, we heard about how a team led by North Carolina State University’s Dr. Michael Dickey had created an electrical wire that could be stretched up to eight times its regular length ... and still carry a current. This was possible thanks to a conductive liquid metal alloy of gallium and indium, contained inside the wire’s elastic polymer outer housing. Now, Dickey's team has developed a new wire that not only can be stretched, but that will heal itself when severed.  Read More

Blood clots are one way in which the body heals itself after injuries on even the tiniest level. The process is fast, reliable and goes on every minute of the day without our being aware of it. Now, a team led by MIT assistant professor of materials science and engineering Alfredo Alexander-Katz is studying blood clots as a new model for producing self-healing materials.  Read More

The material repairs itself in about 30 minutes after being sliced in half with a scalpel ...

Our largest bodily organ is also one of the most remarkable. Not only is our skin pressure sensitive, it is also able to efficiently heal itself to provide a protective barrier between our insides and the world around us. While we’ve covered synthetic materials that can repair themselves or are pressure senstive, combining these properties in a single synthetic material has understandably proven more difficult. Now researchers at Stanford University have developed the first pressure-sensitive synthetic material that can heal itself when torn or cut, giving it potential for use in next-generation prostheses or self-healing electronic devices.  Read More

A new self-cleaning coating technology could mean the end of the tiresome chore of washing...

Nissan’s "Scratch Guard Coat” has been healing fine scratches on the company’s cars for a few years now, and the technology has also made its way into an iPhone case. More recent developments have produced coatings to heal more substantial scratches and scrapes using nano-capsules. Now researchers at The Netherlands’ Eindhoven University of Technology (TU/e) have developed a coating that is not only self-healing, but also promises to free car owners of the tiresome chore of washing the car.  Read More

Researchers at MIT and the University of Pittsburgh have successfully resuscitated non-oscillating Belousov-Zhabotinsky (BZ) gel by exerting a mechanical stimulus: a process akin to the resuscitation of a human heart. By exhibiting a chemical response to a mechanical stimulus (a rare feat for non-living matter), it's claimed the material could lead to the development of artificial skin that would enable robots to feel.  Read More

Gizmag regulars will be well-used to the idea of self-healing materials, and even materials that repair themselves when exposed to light; but a new plastic demonstrated to the American Chemical Society on Monday purports to be the first self-healing material to incorporate a damage-reporting mechanism, almost akin to the bleeding of human skin.  Read More

Velcro is pretty handy stuff, but imagine if there was a soft, stretchy material with the same qualities. Well, now there is. Scientists from the University of California, San Diego have created a self-healing hydrogel that binds together in seconds, essentially copying the Velcro process at a molecular level. The new material could potentially find use in medical sutures, targeted drug delivery, industrial sealants and self-healing plastics.  Read More

Nissan's Scratch Shield iPhone case that employs technology used on cars to self-repair fi...

Just over six years ago, we reported that Nissan had developed a "Scratch Guard Coat" paint designed to repair scratches on not only cars, but on painted surfaces in general. The company has already applied its paint technology to a number of Nissan and Infiniti models, and in 2009 it announced that it would license it for use on mobile phones. It appears there weren't many takers as Nissan has now announced that it has produced the world's first self-healing iPhone case that makes use of the Scratch Shield paint.  Read More

Scientists are creating self-healing electronics, that use liquid metal to instantly resto...

A hard material is impregnated with microcapsules that burst when the material cracks, releasing a stored liquid that hardens on contact with the air, thus repairing the crack ... it’s a system that we’ve recently seen used in a number of applications, including self-healing concrete and polymers. Now, a research team from the University of Illinois is applying it to electronics. They have already created a system that automatically restores conductivity to a cracked circuit in just a fraction of a second.  Read More
