Tattoos are cool right?
Well yeah, unless they betray your unintended emotions and move us one step closer to an Orwellian dystopia where it's impossible to fib.
According to patent applications Google are thinking about just that.
Their Motorola Mobility division has designed a 'electronic skin tattoo' that can be applied to the neck so an individual can communicate wirelessly with a device such as a mobile phone.
Sounds great initially, a logical step in hands-free communication.
But the patent also outlines how it can be attached to a lie-detector.
Or put more technically: "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."
Fortunately the tattoos are removable so you won't have to commit yourself to a life of truthfullness just yet...
