Bite glasses
Rui Zhang, Oliver Amft · 2016
We monitor chewing using 3D-printed smart eyeglasses with Electromyography (EMG) electrodes and bone vibration sensors attached at the eyeglasses frame. We recorded intake of different foods and non-chewing activities and analysed signal waveforms and signal performance. Our prototype showed promising results towards detecting chewing and compensating for non-chewing activities. The bone vibration signal had a typical decaying trend in signal energy during the chewing sequence of each bite. EMG measurements showed only minimal artefacts due to head movement and coughing.
