Nano armor claims to make mobile devices waterproof

A new nano armor coating from a California-based startup promises to protect smartphones against accidental spills or splashes. Startup firm DryWired uses a nano-scale monomer that forms a gas when heated, and becomes a water-tight sealant once it cools, tech site CNET reported. "Indeed DryWired claims that after an ordinary phone has been processed, it will be able to meet the rigorous IPX7 standard for water survivability. Essentially you'll be able to place a DryWired device in three feet of water for a maximum of 30 minutes. Not bad at all," CNET reported. Also, it cited the potential of waterproofing "within reach of all phone and tablet owners." But it said it is not immediately clear how much it will cost to protect a single device, as DryWired plans to sell its technology to either manufactures or resellers. CNET said a machine will apply the nano-armor to mobile devices, which it said are partially disassembled. It said the idea is to protect not just the device's exterior but also its components inside. — LBG, GMA News
