Tooth Sensor: What It Does

People suffering from diabetes, heart conditions, and alcoholism now have an accurate way to measure their food and alcohol intake. This is important for managing diabetes, cardiovascular conditions, and alcoholism. Currently, nothing is available to do this aside from smartphone apps, and apps are tedious and require constant vigilance to assure making the correct data entries.


Tooth Sensor: The Researchers

Tufts University scientists developed an amazing new sensor, only 2 millimeter s on a side, that is attached to the tooth. It measures and transmits readings about glucose, salt and alcohol intake. The device is a combination of a chemical sensor and RFID (radio frequency ID) technology. The sensor does not need a battery, as readings are collected by bouncing radio frequency waves off the tooth. A special device measures the returning signal.

Previous wearable devices for monitoring food intake suffered from limitations such as requiring the use of a mouth guard, bulky wiring, or replacing degraded sensors.

Tufts engineers developed a 2mm x 2mm sensor with a footprint that can flexibly 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 radiofrequency signal.

Though the device has so far been developed to measure sugar, salt, and alcohol; many other variables can be measured. For example, chemical composition of sweat, body temperature, and other parameters.



In the future, radio frequency ID technology will be used to monitor a host of physiological variables. Your health status will be monitored in real time and any medical intervention will be proactive and timely.
