About this study

In recent years, wearable and contactless devices, including smart rings, smart bands/watches, and smart mattresses, have developed rapidly and can continuously collect multidimensional data such as heart rate, oxygen saturation, respiration, body movement, snoring, body temperature, and environmental parameters. Nevertheless, most current consumer-grade or wellness-oriented devices have not been trained and validated using large polysomnography (PSG)-synchronized reference datasets. Their accuracy, robustness, and interpretability in people with insomnia, obstructive sleep apnea (OSA), and other sleep disorders therefore require systematic evaluation.

Leveraging a multicenter clinical sleep-medicine platform, this study will synchronously collect standard full-night polysomnography (PSG) data, continuous body-temperature data, smart-ring sensor data, contactless sleep-monitoring belt data, and indoor environmental monitoring data from the same participant during the same monitoring night. A clinical sleep database will be established with PSG-derived reference-standard labels, strict temporal synchronization, and multimodal features. The database will support the development, optimization, and validation of sleep-staging and obstructive sleep apnea (OSA)-screening models and will provide a data and modeling foundation for subsequent smart sleep-monitoring products, home-based sleep-health management, and clinically assisted screening applications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The sensitivity and specificity of the OSA-screening model

    Taking polysomnography (PSG) as the gold standard, to evaluate the specificity and sensitivity of a new OSA diagnostic system for OSA diagnosis.

    Measured: August 2026 to August 2027

  2. The Cohen's kappa coefficient and overall accuracy of Sleep-staging model

    Agreement and accuracy of sleep stage scoring by the new OSA monitoring system versus PSG (gold standard)

    Measured: August 2026 to August 2027

Secondary outcomes (4)
  1. Stage-specific classification performance of the AI(artifical intelligence) model:precision, recall, and F1 score for each sleep stage.

    Measured: August 2026 to August 2027

  2. Overall accuracy of the OSA-screening model, area under the receiver operating characteristic curve (AUC), and the corresponding 95% confidence interval (CI).

    Measured: August 2026 to August 2027

  3. Exploratory associations of clinical characteristics, subjective scales, body-temperature rhythms, and environmental parameters with PSG-derived sleep architecture and respiratory events.

    Measured: August 2026 to August 2027

  4. Incidence of discomfort related to device wear and other adverse events.

    Measured: August 2026 to August 2027

Questions about this trial

What is this clinical trial studying?

An observational study of Sleep Apnea, Obstructive and Sleep Staging, run by Peking University First Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Cheng Zhang, Dr. (86-10-13611035724, zhangcheng033@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The sensitivity and specificity of the OSA-screening model (time frame: August 2026 to August 2027). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2026.
