It’s been proven numerous times over the years that Google is not always the creator of the most conventional products and the fact that it often has its eyes on the future is quite easy to notice. Think about the self-driving cars, the wearable high-tech glasses or the plan to get everyone to live a lot longer though a new company called Calico.

Well, another rather quirky patent from Google that has just been filed focuses on an electronic skin tattoo that connects to a mobile device and can even be used as a lie detector.

Don’t think of it as your regular tattoo, since this one is not permanent, but rather gets applied to the skin with a sticky substance.

The purpose of the device is to allow the wearer to communicate to someone without having to use their phone directly. Think of it as a James Bond-style secret gadget that lets the user discuss things undetected.

Google suggests that the electronic tattoo could be used by security personnel, such as on stadiums, busy streets or emergency situations.

At the same time, the small gadget could be used as a lie detector. “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 may be nervous or engaging in speaking falsehoods may exhibit different galvanic skin response than a more confident, truth telling individual,” the company said.

Whatever the plans Google has for such an invention, it’s impossible not to think of the secret spy agent movies everyone has seen and how the electronic skin tattoo could come in handy.

We’ll just have to wait and see what Google has in store for the new invention and whether it will ever make anything of it.
