Although it seems that all the advances in mobile phone always move in the same direction: more power, more quality displays… The truth is that there are also other developing very interesting, for example that of materials: lighter, more environmentally friendly with the environment and also more resistant to external elements.
On this last point, Nokia is investigating to improve the hydrophobic surfaces and making it impossible to our phones get wet, them water and therefore fail to function properly. In a video posted on his official blog, which you can find above, Chris Bower of Cambridge University explains how this new surface.
The idea, as other many technological advances, comes from the imitation of nature. In this case in particular of lotus flowers, which repel water perfectly. There is still much to achieve that degree of effectiveness, but as shown by Nokia lets us see it has made enough progress in this matter.
In the video we see a metal surface where water slides as if it were a ball. In fact, the first demonstration that we see is a sort of labyrinth where the drop moves as if it were a marble. In this case we are faced a normal hydrophobic surface.
The following example shows us is clearer. We see how in the screen of a 710 Lumia falls a drop of water and virtually bounces off this. To achieve this degree of rejection, Nokia introduces nanostructures that create a layer of air above the material which allows that the water does not touch the surface.
To get the idea of the difference, Chris Bower aims quite Interestingly. While the hydrophobic surfaces have a contact angle of 120 degrees, the technology being developed by Nokia is of almost 180 degrees. That is, almost absolute.
This technology is currently experimental and There is still so let’s look at it in Nokia phones. The show with the 710 Nokia is just a proof that the technology works. As explained in the blog of the Finnish company technology is almost ready so it is quite likely that we see it in the next generation of phones.
