P2i's Aridion technology could save your bacon if you drop your phone down the loo. And we've all done it.

The most impressive thing I've seen at CES this year involves a wet tissue. Stop sniggering at the back. See all our CES 2012 news.

UK-based P2i describes itselt as 'the world leader in liquid repellent nano-coating technology', a claim it backs up with another: that it is protecting seven million consumer electronic devices from water damage with its Aridion technology. And at CES it is drawing crowds to its booth by treating tissues with Aridion, and then submerging them in water. The tissues emerge unscathed, in a way that those cross-dressing kitchen towel fans from the TV ad would kill for.

It's an impressive sight, and one I can vouch for: reader, I saw the whole process with my very science eyes.

P2i is the force behind the 'SplashGuard' feature of the new Motorola Droid Razr. It's not full water-proofing because, as a spokesman explained, that requires the handset to be watertight, which would affect the acoustics. Waterproofed phones would have to be redevloped from the groun up, he told us. But a further possible application for Aridion would be cases for tablets and phones, as well as the phones themselves.

Currently P2i is working with major electronics manufacturers and OEMs, to apply Aridion to a range of electronics devices, including mobile phones and tablets. On treated devices liquids simply bead up and roll off, rather than sticking to the surface causing damage. And you don't notice it is there: the Aridion coating is one thousand times thinner than a human hair, P2i told us. Because of this, both the internal components and external casing are coated, so as well as preventing water coming in, Aridion helps to protect a device once it has been contaminated.

One phone has been treated, one hasn't: guess which is which

Carl Francis, CEO of P2i, comments: "The risk of accidental liquid damage is increasing at a time when the importance of the cell phone is greater than ever - making its reliability paramount. P2i can significantly improve that reliability."
