Google has filed a patent application for an electromagnetic throat tattoo that has a power supply, an embedded microphone, and a wireless transceiver. The transceiver would be able to connect to a smartphone, smart-watch, or Google Glass. The word “tattoo” is somewhat questionable since it is more of a “flexible substrate” or a sticker. This device would allow people in noisy areas communicate with each other better. The “tattoo” would be able to pick up only the sounds coming from your throat rather than the noisy subway or stadium that you are in.
