Monitoring in real time what happens in and around our bodies can be
invaluable in the context of health care or clinical studies, but not so
easy to do. That could soon change thanks to new, miniaturized sensors
developed by researchers at the Tufts University School of Engineering
that, when mounted directly on a tooth and communicating wirelessly with
a mobile device, can transmit information on glucose, salt and alcohol
intake...Tufts engineers sought a more adoptable technology and developed a sensor with a mere 2mm x 2mm footprint that can flexibly conform and bond to the irregular surface of a tooth. In a similar fashion to the way a toll is collected on a highway, the sensors transmit their data wirelessly in response to an incoming radio-frequency signal. more
Just in case you were disappointed that this was not a story about a mysterious tooth implant...
