London, Mar 21 (ANI): 'Nokia' has applied for a patent on tattoos that would sense and alert a user when his mobile phone rings or has low battery.
Using metal ores, the 'tattoo' would vibrate and would feel like tingling sensation and the user would have to scratch their arm to dismiss the alert.
As the tattoo is inserted under the skin, however, users would have to undergo a minor surgical procedure to take advantage of the new technology, which Finnish phone company says would only be activated after scars have healed.
The technology could also be applied superficially, but would be less resistant to wear and tear.
Communicating using different sequences of single or multiple pulses, the tattoo could theoretically do different things for messages, emails or warnings.
"Prior to using the ferromagnetic inks for attaching to human skin, the ink material may be exposed to elevated temperatures to cause demagnetisation," the Telegraph quoted Nokia as saying in the US patent application.
"Such demagnetized ink is then used for creating an image by dispersing the ink material on or under the skin to make a functional, tattoo like image. Once the apparatus is settled and the skin cured, the user with the functional image may use permanent magnets to magnetize the functional image on the skin again," the application reads.
The application was filed this month at the US Patent and Trademark Office. (ANI)
