Google files patent for a neck tattoo with lie detector capabilities and a microphone

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. The application reads:

Mobile communication devices are often operated in noisy environments. For example, large stadiums, busy streets, restaurants, and emergency situations can be extremely loud and include varying frequencies of acoustic noise. Communication can reasonably be improved and even enhanced with a method and system for reducing the acoustic noise in such environments and contexts.

Google also suggests that it could be used in conjunction with a lie detector to tell when a user is speaking falsely, based on skin response.

Optionally, the electronic skin tattoo 200 can further 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.

Obviously this Google neck tattoo is still in the early stages of development, but it does raise some interesting questions as to what else Google is secretly working on.
