Nokia has filed a patent for a tattoo that would be able to receive magnetic waves from a phone and send a vibration to the user's skin to indicate an incoming call. The tattoo inks contain ferromagnetic ink, which is ink with iron or iron oxide. Like ringtones, users can customize the magnetic waves for different people and to distinguish between phone calls and texts. Users are also able to choose the image and location of the tattoo.
