A group of researchers and scientists working out of the University of Buffalo have developed a high-tech nutrition-monitoring necklace that is designed to monitor your dietary intake.
The AutoDietary device is capable of staying on top of your caloric intake by listening to the sounds that you make while chewing and swallowing different kinds of food. The system then sends relevant data to a companion smartphone app before providing a range of recommendations, and will tell you if you are chewing too fast or if you are consuming too much of a particular kind of food.
This nutrition-monitoring necklace's functioning is not perfect by any means, but is still capable of detecting the food accurately 85 percent of the time. Future editions may feature a bio-monitor component that will also study your blood sugar levels, providing a more wide-ranging assessment of your health.
