Military has microphones on back teeth for invisible, hands-free radio secure communications

The future of battlefield communications is resting comfortably on the warfighter’s back teeth. Next time you pass someone on the street who appears to be talking to themselves, he literally may have voices inside his head ... and be a highly trained warfighter on a dangerous mission. The Pentagon has inked a roughly $10 million contract with a California company to provide secure communications gear that’s essentially invisible. Dubbed the Molar Mic, it’s a small device that clips to a person’s back teeth. The device is microphone and speaker to enable the wearer to transmit without any conspicuous external microphone and receive with no visible headset or earpiece.
