Nokia has invented a tattoo which will vibrate when phone rings!!
Sounds like something out of science fiction, but it's being reported by the Wall Street Journal that Nokia has applied for a patent that does just that. The patent describes 'a material attachable to skin, which is capable of detecting a magnetic field and transferring a perceivable stimulus to the skin.' The practical use of this, is a removable vibrating tattoo. While the technology isn't specific and could be used in many different ways, the patent makes it clear that embedding the material is the main use. It talks about using 'ink enriched by ferromagnetic or paramagnetic compounds.'
