iES : In-ear Bioelectrical Sensing System

Project Description

Sleep occupies nearly a third of human life and acts as a critical daily function to help human body balance and regulate its vital system. Precisely doing sleep quality assessment requires a simultaneous evaluation of three fundamental bioelectrical signals generated by brain activities, eye movements, and muscle contractions during sleep. However, the “gold standard” sleep diagnostic tool is currently cumbersome, expensive, and inconvenient in use. This work aims at developing a costly effective mobile in-ear sensor capable of non-obtrusively capturing such three important biosignals with high fidelity and accurately monitoring sleep of sleeping users.
