Wireless 'Tooth Tattoo' Detects Potentially Harmful Bacteria Before It Enters The Body

“People are going to be bionic.” So says Princeton University’s Michael McAlpine, a firm believer of the idea that humans, possibly within just five to ten years, will wear electronic devices all over the body for various purposes. Whether it’s integrating cardiac sensors into the body to monitor abnormal beats or in this case, fixing a flexible electronic circuit atop tooth enamel to detect potentially-harmful bacteria before it ever gets the chance to enter the body.
