Necklace Tracks Food Intake by Analyzing Chewing Sounds
From: Medical Design Technology - 03/16/2016

AutoDietary is like Fitbit and other wearable devices. Only instead of
tracking burned calories, it monitors caloric intake - in other words, what
we eat - at the neck.

AutoDietary wraps around the back of the neck like a choker necklace. A tiny
high-fidelity microphone - about the size of a zipper pull - records the
sounds made during mastication and as the food is swallowed. That data is
sent to a smartphone via Bluetooth, where food types are recognized.

AutoDietary is able to accurately identify the correct food and drink 85
percent of the time.
