Screening and Diagnostics
Discover Sunrise – At-Home Sleep Testing Made Easy
Sunrise is a lightweight, 3-gram sensor worn on the chin during sleep. It’s non-invasive, single-use, and designed to deliver accurate sleep data—all from the comfort of your own bed, with no need for a hospital stay.
Approved by NICE (2024) for use in home sleep testing, Sunrise represents one of the most significant innovations in sleep diagnostics in the last 20 years.
- High level of accuracy
- Used at home
- Non-invasive
- Disposable & recyclable
- Cost-effective
Sefam Medical UK is the official UK supplier of the Sunrise device.
How It Works
During sleep, the brain maintains upper airway openness by controlling muscles attached to the mandible (lower jaw). The mandibular movements triggered by this brain activity reflect how the sleep centres regulate breathing and transitions between sleep stages.
Sunrise captures and interprets these movements using AI to assess:
Total Sleep Time
Micro-arousals
Sleep staging
Obstructive apnoea and hypopnoea events
Respiratory effort (RERAs)
Head position

Go beyond AHI
The most exhaustive home sleep test
As efficient as a standard sleep study
- Sleep wake detection
- Sleep stages
- Apnoeas/Hypopneas
- Estimated AHI (with central component)
- Head position
- Sleep efficiency
Unique to the Sunrise Signal (mandibular movements)
- Micro-arousals
- Respiratory effort
- True sleep time
- Sleep bruxism
- ORDI including Respiratory events related arousal (REFAs)
Upcoming features
- Cheyne-Stokes breathing
- Central Apnoeas
- Mouth openings
- Monitoring of prescribed treatments
Why Mandibular Movement Matters
Unlike traditional sleep studies that rely on EEG, belts, and multiple electrodes, Sunrise uses mandibular movement patterns to analyse sleep physiology. These movements reflect:
Brainstem respiratory and sleep centre interactions
Transitions between wakefulness and sleep
Changes in upper airway muscle activity
AI then decodes the amplitude and frequency of these signals to identify:
Sleep/wake states
Micro-arousals
Respiratory effort
From this, Sunrise accurately identifies apnoea and hypopnoea events—delivering clinical-grade data with greater comfort and convenience for patients.

Clinical Advantages
No need for EEG, EMG or EOG
No nasal cannula or chest/abdomen belts
Validated against conventional polysomnography
AI-powered, automated analysis
Faster access to diagnosis for patients

Frequently Asked Questions
Yes, the Sunrise version 1 is MHRA approved for screening for and assisting clinicians in diagnosing sleep apnea in aged >3 years and above.
Sunrise measures signals from mandibular jaw movements (MJM) via an accelerometer and gyroscope in the sensor. By MJM, it also detects obstructive respiratory disturbances (ORDI) , identifies sleep states, Obstructive Sleep Apnea (OSA) severity (non-OSA, mild-OSA, moderate-OSA, severe OSA), generates sleep structure information (total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), arousal index (AI) and head position. Sensor data collected is integrated in a PDF report for further interpretation and diagnosis by the healthcare provider.
No, a new sensor is needed for each subsequent sleep test.
Yes, the raw data marks periods of obstruction when the jaw opens (mandible drops as measured by the accelerometer) while at the same time there is a significant increase in the amplitude of the mandibular movements denoting increasing effort to breathe (rotation of the jaw as measured by the gyroscope). Central events also reveal a jaw opening (mandible drops as measured by the accelerometer) while simultaneously there is a decrease or complete absence of the amplitude of the mandibular movements (absence or significant decrease in the rotation of the jaw as measured by the gyroscope).
Wakefulness is clearly discriminated and can be confirmed via visual inspection of the raw data of mandibular jaw movements due to their highly variable, often fast, and unpredictability in both amplitude and frequency. This was demonstrated in a validation set of 226 simultaneous synchronized PSG recordings with a sensitivity of 88% (95% CI, 71–99%) and a specificity of 94% (85–98%).
During REM sleep, mandibular jaw movements are preserved but show marked variability in amplitude and frequency that is characteristically unpredictable. The algorithm performed well in detecting REM sleep with a sensitivity of 83% and a specificity of 89% when compared to simultaneous PSG on 1026 patients.
In general, the only patients that would not be candidates for testing with the sensor are bearded individuals that are unwilling to shave the area just below their lip or patients with conditions affecting the rotation of the condyle in the temporo-mandibular joint.
Yes, a prepaid return shipping envelope is included in every Sunrise sensor box for the purposes of recycling.
