Researchers at National Taiwan University have created a tooth-embedded sensor that will catch you in an unhealthy act, whatever it may be, and lets your doctor know so he can shame you during your next checkup. The sensor consists of a tiny circuit that fits inside a tooth cavity and can be rigged into dentures and dental braces. The circuit is able to recognize the jaw motions of drinking, chewing, coughing, speaking, and smoking, and the results get sent directly to your doctor’s smartphone.
To test the prototype, Hao-hua Chu and his team at the university secured the sensor into eight people, and the results were promising. Although the prototype is hooked up to an external wire, the sensor correctly identified oral activities and motions 94% of the time. The next step will be installing a rechargeable internal battery and wireless communication. Researchers are also looking into constructing a recharging and storage unit “similar to that of an electric toothbrush,” since some users must remove artificial teeth before sticking the sensor in.
