Motorola has filed a patent application for an electronic skin tattoo, which is proposed for use as a smartphone microphone and wireless transceiver.
Incorporating power supply build-up to receive energising signals from a personal area network, the new temporary tattoo allows wireless communication with the user’s smartphone, a battery and controller.
The new tattoo is proposed to be applied to users’ neck, which would pick sounds produced by their voice by interpreting vibrations and variations of muscle or tissue from their voicebox.
Users are still required to use headphones or the built-in receiver to listen in to the incoming audio.
Motorola Filing said: "Mobile communication devices are often operated in noisy environments. For example, large stadiums, busy streets, restaurants, and emergency situations can be extremely loud and include varying frequencies of acoustic noise.
"Communication can reasonably be improved and even enhanced with a method and system for reducing the acoustic noise in such environments and contexts," the filing said.
In addition, the latest patent application also talks about a galvanic skin response detector, which may convert the device into a lie-detector.
