Nokia files patent for ringing cellphone tattoo

The Swedish phone-maker has filed a patent for a tattoo that would vibrate when a phone call was coming in or when the phone battery was running low.

The person would scratch their arm to get rid of the alert and it would feel like a tingling sensation. The tattoo is a material that attaches to skin, detects a magnetic field and then transfers that stimulus to the skin.

It could be the next big thing.
