Scientists demonstrate how to become a blabbermouth without uttering a word

A team of researchers at the National Taiwan University in Taipei are currently perfecting—if that is the right word—a device that could inform doctors and dentists whether and when their patients have been eating, drinking and smoking, according to a story by Adam Clark Estes in Gizmodo.

Mouths make unique motions depending on whether they are being used to eat, drink, smoke or talk, and the team’s Bluetooth-ready fake tooth records these motions.

In a study with eight participants, the tooth recorded their mouth activities with 94 percent accuracy.

The prototype was connected to a computer and power source with a small wire leading out of the mouth, but the final version will be Bluetooth-enabled and battery-powered.
