Google Tattoo: Sticker-sized voice transmitter that's also a lie detector

It's being called the "Google Tattoo" -- and it could be the future of hands-free telecommunication.

Motorola Mobility, which is owned by Google, has submitted a patent application for its design of a tiny electronic device that sticks onto your neck like a piece of adhesive tape and connects wirelessly with your mobile phone at close range.

Unlike a real tattoo, the Google device would not be permanently embedded in your skin, but could be stuck on and removed.

Google says the tattoo could also be configured to work with a video gaming system, wearable computer and other types of electronics.

An electronic lie-detector?

Google further suggests that its electronic tattoo could be used as a tiny, portable lie detector. In the patent application, it says the device could include "a galvanic skin response detector to detect skin resistance of a user. It is contemplated that a user that may be nervous or engaging in speaking falsehoods may exhibit different galvanic skin response than a more confident, truth telling individual."

Just because it's patented, however, doesn't mean the Google Tattoo will actually be manufactured as envisioned, or that all of these proposed features will be brought to market.
