This Tiny Tooth Sensor Could Track Your Diet and Health #WearableWednesday

via Wearable-Technologies

High-tech wearables have become a part of our life. They are everywhere, from our wrists to our pets, and now, they are in our mouths!

Scientists from Tufts University have developed tiny sensors that attach to your teeth, and monitor your diet and health in real time. The sensor, when communicating wirelessly with a mobile device, can transmit information on glucose, alcohol and salt intake. Researchers note that future adjustments of these sensors could make them detect and record a wide range of chemicals, nutrients, and physiological states.

Previously marketed wearable devices for monitoring diet encountered obstructions such as bulky wiring, requiring the use of a mouth guard, or needing frequent replacement as the sensors quickly became corrupted. The Engineers at Tufts sought a more acceptable technology and created a sensor with a tiny 2mm x 2mm footprint that can easily adapt and bond to the uneven surface of a tooth. The sensors transmit their data wirelessly via an incoming radio frequency signal.
