This sounds like its made up. It says at the end of the article it's just a concept-an idea. That doesn't mean they've ever even built one. If they had the tech to make a phone to fit between your skin, phones right now would be a lot smaller too. Forgive the pessimism, I think the idea is cool, but it'll take a little more than a vague drawing and a picture of a guys arm with ink pen scribbles on it to convince me.
