It used to be an urban myth that people could pick up radio signals from a filling in their tooth.
But next time someone seems overly orally-concentrated, you might want to pay attention.
An English engineer has designed a brand new tooth implant that can communicate with radios, cell phones and computers. The device, which can be implanted in a tooth during routine dental surgery, converts digital signals into sounds and then transfers the sound from the tooth to the inner ear. That means consumers can have access to information any time, anywhere, without anyone knowing. So while your co-worker appears to be focused on your presentation, he could actually be getting information on his portfolio.
The device isn't out on the market yet, but it's on display at the Science Museum of London. It's being billed as the first commodity-based in-body product. How's that for a brand new category?
