My mom may not like that I have tattoos, but I'm sure she'd like even less if I had a tattoo of a microphone tattooed on my throat. That's what Motorola is proposing, with a patent for a wireless mic that's tattooed on the throat and connects to a smartphone. Not only would it allow you to have "reasonably" improved communication, but it could also be used to detect lying. And it could light up! Hear that, Mom? This thing might actually be useful.
