Vibrating magnetic tattoos may one day be used to alert mobile phone users to phone calls and text messages if Nokia follows up a patent application.
The Finnish company has described the idea in a filing to the US Patent and Trademark Office.
It describes tattooing, stamping or spraying “ferromagnetic” material onto a user’s skin and then pairing it with a mobile device.
It suggests different vibrations could be used to create a range of alerts.
