Although wearables don’t make as much noise as they did a few years ago, The truth is that there are firms that continue to bet heavily on them. The most obvious examples are Apple, Fitbit and Xiaomi, whose range of ‘wearable’ devices translate into bracelets and watches. The objective of these, beyond seeing notifications, is to be able to monitor our health status: steps walked, calories burned, kilometers traveled, etc., but they have nothing to do with this device, able to record everything the user eats and drinks.
The wearable is a sensor that is placed on the teeth and connects wirelessly with your smartphone. This small sensor is capable of recording sugar, salt and alcohol intake, although researchers at Tufts University (Medford, Massachusetts) believe that could help people manage their nutritional trends. On the other hand, the wearable could help monitor dental health, and even detect well-being problems such as fatigue through saliva. The device measures two square millimeters, and unlike previous similar technologies, it can be used without a mouth guard.
And how it works? You will ask yourself. Well, this sensor has a ‘bioresponsive’ layer that absorbs nutrients and food products, which generates changes in the electrical properties of the sensor. The device’s antennas absorb and transmit a specific wave spectrum and intensity, which is received on the user’s device, as pointed out in Alphr.
The most interesting thing is that its application is not only focused on teeth. According to Dr. Omenetto, author of the study,
The problem is that the sensor lasts only a couple of days, although through research their autonomy could be extended. It is not known when it will be available for sale to the public, or if it will ever be. It is a curious invention that shows how technology goes beyond sending WhatsApp and taking photos, even improving the real life of people.
