Tiny nandihalli will allow electronic devices to regenerate itself if damaged

Electronic devices of various kinds every day are becoming more complex and miniature, and the exact same drastic changes occur in technology used in production and repair of these electronic devices. But in some cases the complexity of electronic devices makes it impossible the process of detection of arising fault and fix it, for such "heavy" cases, the researchers from the University of California in San Diego have developed a new technology of self-healing that uses tiny nandihalli able to independently search for and sarasawati minor mechanical damage, for example microcracks.

"Modern electronic circuits have a very high degree of difficulty, in order to verify this, just look at the circuit Board from your smartphone or tablet," says Jinjing Lee (Jinxing Li), "But all cracks, even the smallest, can interrupt the path along which electric current flows, which eventually leads to device failure. Conventional electronics can be recovered by traditional soldering, but the repair is the most advanced nanoscale electronics requires new and innovative approaches".

"If you cut your finger, platelets (thrombocytes) automatically isolate the injury from the environment and will help to start the healing process" says, "Using this as an initial idea, we designed an extremely small robots that perform platelet function in relation to the electronic system".

Nanorobots are nanoparticles of gold and platinum, and they are driven by the same hydrogen peroxide solution (hydrogen peroxide). The platinum acts as a catalyst that breaks down peroxide to water and oxygen, the bubbles of which move to make the nanoparticles. When moving a nanoparticle into the region of the cracks, they fill her, penetrating all its corners due to the small size. And since the nanoparticles are made of conductive materials, this allows you to restore electrical contact in place of the crack.

Such nanoparticles nanorobots are ideal for the recovery of certain electronic components that are extremely difficult or impossible to repair in other ways. For example, they can be used to restore conductive layer of solar panels that are constantly exposed to sharp temperature fluctuations that, in turn, causes the appearance of many microcracks. In addition, this same approach will allow you to "heal" flexible sensors, batteries and other flexible electronics, for which it is impossible to touch an ordinary soldering iron.

In addition, this technology, which uses slightly different materials and kind of "fuel" can be used in medical applications for drug delivery directly to the point of their application. Now scientists at UCLA are working toward the creation of nanorobots-mandviwalla that will be able to function inside the human body and which can be used for the treatment of various diseases, including infectious.
