Ear-EEG is being investigated as a way to accurately monitor sleep at home, reports BioMedCentral.

In our study: 9 people were equipped with both polysomnography and ear-EEG, and spend the night in their own beds. Afterwards, we used the ear-EEG measurements to automatically (using a computer algorithm) score their sleep, meaning that we determined at what time of night they were in different sleep stages (REM sleep, deep sleep etc.). We then measured how much our ear-EEG based sleep scoring agreed with the clinician’s scoring, when she used the polysomnography data.
