The power of Self Healing: Latest Mobile Technology
Just
when we think that there is a limit to the ability of science and technology’s
evolution, we are proven wrong at the very next moment. The generation of
mobile phones has seen revolutionary technological advancement and everyday
astonished with something new. Just when
I thought what more can be done with the hardware of a smartphone besides the
screen size and the finish of the looks, the scientists made me shut up by
introducing the self healing screen. Oh yes! You read it write, the mobile
screen can heal itself! Is that even possible?
Well, read on.
The
basic technology is based upon properties of materials which change in
accordance with the nature of the surroundings. The materials as designed such
that they alter their properties as per the changes in the surrounding. With
the increasing sophistication and understanding of the nano-materials,
scientists will be soon be able to manufacture materials that will need no
maintenance, how’s that? A onetime investment will give you a product for a
lifetime.
Talking about the current technology that mobile
phones will use, the layers of protective film is said to have three
sub-layers, each of them having a specific purpose and role to play in the self
healing of the surface. The top sub-layer is supposed to be hydrophobic, i.e.
it repels water. To keep the other sub-layers protected from the adverse
effects of exposure to water. The second sub-layer is consisting of polymer
‘stalks’ which form the intermediate between the ‘active’ ingredients in the
bottom most layer and the exposed layer on the top. The working principle is
quite tricky to understand but if we talk plain English, we can understand it
in this way. Whenever the top layer is scratched , some part of the top layer
is removed and the polymer stalks are exposed to the environment.
When this
happens the concentration gradient created forces the ‘active’ ingredient is
forced to crawl up the layer of polymer stalk and the top layer gets
replenished. And your gadget looks as good as new, free from any scratches.
The potential of the
exploring this technology is huge and much work is being done in the same.
Beyond, electronic gadgets this technology can be used on cars, which would
mean you never have to worry about bruises on your dream car. On airplanes,
meaning no dust deposits and thus less air resistance, less fuel consumption,
lesser air fare ! The applications are
endless and the opportunities as vast as ocean. Keep exploring.
