CNN writes about ten new inventions. Invention number ten is a tooth tattoo sensor. “The thus-far unnamed sensor is outfitted with miniscule electrodes and a wireless coil – allowing it to be powered by, and transmit information to, a remote device. When it detects the kind of bacteria that causes decay or disease, it pings that device, letting its wearer know there’s a problem brewing. Depending on which bacteria it’s programmed to detect, the sensor could also be used to watch for other types of illnesses.”
