Filed under: CellphonesPlenty of waterproof phones and other small weatherproof devices have made it off the assembly lines and into our clumsy clutches, but P2i, a small spinoff company using tech originated within the Defence Science and Technology Lab in England, could be bringing waterproof gadgets to the masses. The Ion-Mask is a special invisible coating that is chemically bonded to the device and repels water. It should allow waterproofing to make it into devices that are too small for the seals that are usually used to do the trick. Devices can have joins and gaps coated for a general level of water repellence, or have individual components treated for even more protection. The tech was originally designed to repel toxic vapors and liquids from soldier uniforms, and could also be making its way into athletic shoes. Three leading phone makers are apparently in discussions over using the tech in upcoming phones.
