If you're wondering how much food you've eaten today and how many calories it brings you, there's a new device that will calculate it all for you.
Scientists in Taiwan have created an artificial tooth with a sensor that can track not only how much we eat, but also how much we cough, drink and even talk.
The creators are engineers and made the new invention under the guidance of Chu Hao-hua, who works at the National Taiwan University.
The sensor, which is built into the artificial tooth, is small - 4 mm by 10 mm. It also has three axes of sensitivity. In addition, the data received can be sent via Bluetooth to a mobile device.
Specialists have compared the movement of teeth in each individual action - coughing, talking, drinking or eating. In addition, the device was tested on eight volunteers - the sensor was glued to a real tooth of each of the participants, and no artificial molar was placed.
During the testing, wires were used to transmit the received data to an external device - at the same time, they prevent the danger of swallowing the sensor in case it comes off the tooth. When the data classifier setting was general, the accuracy of the recognized actions was about 60 percent.
With individual adjustment, however, the accuracy was over 90 percent. This artificial tooth with a built-in sensor will be able to help doctors, because it will be able to collect accurate information about the eating habits of its patients, its creators are convinced. In this way, each doctor will be able to monitor whether his patient follows the diet strictly and accurately.
In addition, it will be able to track the breathing of each person, as long as it is adjusted individually for each. In appearance, the tooth with a sensor looks like a completely normal and normal molar.
Such devices also allow you to track the interaction between the tongue and teeth during speech, and to record the gnashing of teeth at night during sleep.
Scientists believe that such devices are Tooth Tattoo - sensors that are based on graphene, which detects the content of bacteria in saliva, in addition to detecting the breath and X2 xGuard - this is a device used by athletes. It tracks exactly how many blows to the head they received.
