nk497 writes: A Motorola Mobility patent application has proposed using an "electronic skin tattoo" as a smartphone microphone and wireless transceiver. The temporary tattoo would also include a "power supply configured to receive energising signals from a personal area network", according to the filing with the US Patent and Trademark Office. It would be applied to "a throat region of a body" — otherwise known as the neck. Motorola thinks the technology would be ideal for noisy environments, such as large stadiums and busy streets, or in emergency situations.
