Self-healing

Electronics

Electronic material self-heals and functions even after being cut in half

If you've ever bent a piece of wire or plastic back and forth until it broke, you understand one of the problems inherent in flexible electronics. The more circuits and connectors flex, the higher the likelihood they'll break. While we've seen self-healing chips, gels and microcapsules before, a new material out of Pennsylvania State University (Penn State) brings auto-repair to dielectrics – the materials that insulate electric currents.Read More

Coating highlights microscopic cracks, before they lead to disaster

Whether they're on airplanes, bridges or pipelines, even the tiniest of cracks can fast lead to catastrophic failures. That's why it's important to identify them as early as possible, before they get out of hand. With that in mind, scientists at the University of Illinois have created a new polymer coating that can be applied to a wide variety of structural materials. When those materials crack – even a little – the polymer changes color to let inspectors know that something's up.Read More

Self-adaptive composite heals itself and returns to its original shape

Self-healing materials that can repair cracks and other damage automatically have been the dream of scientists and engineers for decades, but a team of scientists at Rice University have come up with a new twist. It's a Self-Adaptive Composite (SAC) that is not only self healing, but also has reversible self-stiffening properties that allow it to spring back into shape like a sponge.Read More

Self-healing gel to repair and connect electronic circuits

Researchers at The University of Texas at Austin may have found a solution to one of the key problems holding back flexible, bendable electronics and soft robotics from mass production. Electronic circuits tend to crack and break when repeatedly subjected to bending or flexing, but a new self-healing gel may automatically repair these flaws as they develop.Read More

Self-healing bioplastic – just add water

Imagine if things like undersea cables or medical implants could simply heal themselves back together if severed – it would certainly be easier than having to go in and fix them. Well, scientists at Pennsylvania State University are bringing such a possibility closer to reality. They've created a moldable polymer that heals itself when exposed to water – and it's based on squid sucker ring teeth.Read More

Self-healing material could plug holes in space ships

As the movies have shown us, space travel is an intimidating prospect, what with the possibilities of running out of air, the rocket engines conking out, or the shipboard computer deciding to bump off the crew. Another danger is fast-flying orbital debris piercing the hull. Scientists may be on their way to a solution to that one, however, in the form of a new self-healing material.Read More

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

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.Read More

IBM discovers first new class of polymers in decades

The chemical tree got a bit of a shake this week with scientists at IBM announcing the discovery of the first new class of polymer materials in decades. Discovered using a combination of lab experiments and computer modelling, the new plastics have properties that could potentially have a huge impact in manufacturing, transportation, aerospace, and micro electronics.Read More
