Tiny Tooth-Mounted Sensors Track Food Intake

Monitoring in real time what happens in and around our bodies can be invaluable in the context of healthcare 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. In research published in the journal Advanced Materials, researchers note that future adaptations of these sensors could enable the detection and recording of a wide range of nutrients, chemicals, and physiological states.
