The future of mobile phones goes through the Neodymium



Innovations in the field of smartphones happen frequently, but not all are equally important. A team of engineers has developed a material capable of self - repair in record time.

In our day to day we use multitude of devices but surely the one that more times we take and support our mobile. It is also the one that most bother us with aesthetic problems.

That is why the advances related to the increase of resistance or durability of smartphones seem so striking.


Mobile phones that self-repair

A few years ago LG introduced the LG G Flex , a device that stood out for its flexible curved screen feature, which attracted no attention outside specialist circles too.

But that mobile also had a feature that only saw each other again in the version that happened, the LG G Flex 2: autorreparaba it.

The material of the back shell was created by a polymer capable of modifying its position and correcting small scratches if we waited long enough. In the video we see the process.


New, more advanced technology

The improvement over this technology comes from the University of California, San Diego, where engineers have developed a new technique able to fix cracks up to 3 mm thick.

Besides that greater repair capacity is the fact that instead of several minutes or hours the new technique, based on magnetic ink, is capable of performing the repair at 0.05 seconds. That's almost the definition instantly.


Interesting Properties of a Mixed Metal


The material used is neodymium , a soft metal having electrical properties but no electrochemical driving. To improve the possibilities of the products have been mixed with coal, expanding its potential use.

This metal however has the problem that it needs a magnetic preorientation so if we cut it, "want" self-repair, which is why researchers have fabricated the test pieces with activated magnetic fields that predisposed the neodymium in one direction.

Thus, when the fields are extinguished the neodymium is stable, but if we cut it its inclination will be to rejoin, which is what visually looks like a repair.


Use on mobile and other devices


It is clear that an improvement of that caliber will be interesting not only for the exterior finishes of the devices but also for circuits and sensors that are repaired automatically when they are damaged.

More than a correction with respect to what already introduced LG, it is something that can be printed on top of other materials if necessary.

We must not lose sight of the fact that we are in a very primitive stage and that as we have seen in the examples of the videos although the repair exists is not for the perfect moment, and a not very abrupt movement could disconnect the elements.
