NCT ID NCT06255613
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether a wearable ring and a small body sensor can accurately diagnose sleep-disordered breathing, including sleep apnea. About 79 adults with suspected sleep apnea will wear the devices during an overnight sleep lab test. The goal is to see if the ring's readings match the standard sleep study results, potentially offering a more convenient 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.
Active substance
Belun Ring and Belun Cor body sensor (wearable devices)
What this could lead to
If successful, this could provide a simpler, at-home way to diagnose sleep apnea without needing an overnight stay in a sleep lab.
What could go wrong
This is a small, early-stage study with only 79 participants, so results may not apply to everyone. The device may not be as accurate as the gold-standard lab test.
