Summary

This study is testing whether wearable devices like activity trackers, EEG headbands, and smartphones can accurately measure sleep stages. Researchers will compare these devices to standard sleep lab tests (polysomnography) in 96 healthy volunteers and people with sleep disorders. If the devices prove reliable, they could offer a simpler, more accessible way to diagnose sleep problems at home.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could lead to a reliable, at-home method for diagnosing sleep disorders without needing a sleep lab.
What could go wrong: This is an early-stage validation study with only 96 participants. The wearable devices may not match the accuracy of standard polysomnography, and results may not apply to all sleep conditions.
