tooth-mounted diet tracker

Tooth-mounted diet tracker

Scientists at Tufts University School of Engineering, USA, have developed a tooth-mounted sensor that is designed to not only track every bite the wearer takes, but also record what it contains.

The 2mm x 2mm sensor can be bonded to the surface of a tooth and detects different chemicals, such as alcohol, salt and sugar, through its ‘bioresponsive’ layer and then sends the data wirelessly to a mobile device. The design itself is simple and inexpensive, meaning that it could become widely available.

Monitoring in real time in this way could be beneficial for clinical trials and for healthcare professionals requiring reliable dietary data to help their patients.
