Title: A Lightweight And Inexpensive In-ear Sensing System For Automatic Whole-night Sleep Stage Monitoring

Authors: Anh Nguyen, Raghda Alqurashi, Zohreh Raghebi, Farnoush Banaei-kashani, Ann C. Halbower, and Tam Vu

Abstract:
This paper introduces LIBS, a light-weight and inexpensive
wearable sensing system, that can capture electrical activities
of human brain, eyes, and facial muscles with two pairs
of custom-built flexible electrodes each of which is embedded
on an off-the-shelf foam earplug. A supervised nonnegative
matrix factorization algorithm to adaptively analyze
and extract these bioelectrical signals from a single
mixed in-ear channel collected by the sensor is also proposed.
While LIBS can enable a wide class of low-cost selfcare,
human computer interaction, and health monitoring applications,
we demonstrate its medical potential by developing
an autonomous whole-night sleep staging system utilizing
LIBS’s outputs. We constructed a hardware prototype
from off-the-shelf electronic components and used it to conduct
38 hours of sleep studies on 8 participants over a period
of 30 days. Our evaluation results show that LIBS can monitor
biosignals representing brain activities, eye movements,
and muscle contractions with excellent fidelity such that it
can be used for sleep stage classification with an average of
more than 95% accuracy.
