Researchers at Tufts University have developed an amazing new sensor, only 2 millimeters on a side, that can be attached to the tooth and measure and transmit readings about glucose, salt and alcohol intake. The work was supported by U.S. Army Natick Soldier Research, Development and Engineering Center, the National Institutes of Health (NIH; F32 EB021159) National Institute of Biomedical Imaging and Bioengineering and the Office of Naval Research. The device is a combination of a novel, unpowered chemical sensor coupled with RFID (radiofrequency ID) technology. This allows the device to work without requiring a battery, as readings are performed by bouncing RF waves off of it while a special device measures the nature of the returning signal.
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. In research to be published soon 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.
