Someday soon, you may pick your own magnetic resonance, in the form of a tattoo linking you to your personal possessions. BBC reports:
Vibrating magnetic tattoos may one day be used to alert mobile phone users to calls and text messages.
The idea…in a filing to the US Patent and Trademark Office…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.
The filing also suggests that the magnetised marking could be used as an identity check. By picking a certain shape the user could create a “specific magnetic impedance” – effectively their own magnetic fingerprint. This could act as a “password” and gives the example of a laptop refusing to display content on its screen unless it verifies its user is close by.
