(PhysOrg.com) -- Nokia, the Finnish smartphone maker, has filed a patent for a haptic communication system where tattoos will send you vibrations so you know who is calling. Your ferromagnetic ink tattoo would vibrate based on signals sent from a phone and you could customize the tattoo-phone-linked system. A special ferromagnetic ink on your skin, painted on like a tattoo, could send the various signals. The patent, filed March 15 by Nokia, proposes a material "capable of detecting a magnetic field and transferring a perceivable stimulus to the skin, wherein the perceivable stimulus relates to the magnetic field." The US patent application 20120062371 is described as a topical haptic notification system.
