The patent refers to an electronic neck tattoo that acts as a microphone for mobile electronic devices.
The US Patent and Trademark Office issued the patent (20130297301) on 7 November.
According to its claims, the electronic skin tattoo includes an embedded microphone, which could directly capture sound emanating from a throat and transfer it to a smartphone or other devices.
The tattoo would be close to the user’s throat. It could be placed with adhesive to either humans or animals, or inserted in a band or collar, according to the patent.
The device would be rechargeable and users would be able to connect through Bluetooth, Wi-FI and other networks, which will eliminate background noise that plagues cellphone devices.
The patent was filed on 3 May 2012.
