It’s no secret that Google thinks big when it comes to crazy, innovative technologies, and that appears to be just what the company is doing with its latest patent filing (via The Register). Google’s Motorola Mobility division, a year ago, filed for a patent relating to a temporary neck tattoo that can serve as a lie detector and includes a built-in microphone.
It’s an incredibly out-there concept. Essentially, Motorola says you will be able to apply the tattoo with a sticky substance to your neck and wirelessly connect it to a mobile device.
The patent application suggests a couple of potential use cases. For one, Google points out that it could be used by security personnel that work undercover or in noisy environments.
