Sleep Apnea Monitoring

This project utilizes a geophone-based system for overnight sleep apnea monitoring. The system estimates key sleep and breathing metrics, including apnea-hypopnea index (AHI), apnea severity, and total sleep time (TST), and supports accessible home screening and long-term monitoring as a complement to clinical polysomnography (PSG).

Preliminary Results

Preliminary work shows that mobile sensing signals can capture meaningful patterns related to sleep-breathing behavior. The next step is to improve robustness across different users, sleeping environments, and sensing conditions.
