Place
Place the MedBug strip on top of the mattress at mid-chest, under the mattress protector, follow the study protocol, and leave it in place for multi-night recording.

Mattress-based sleep research.
Multi-night staging and breathing analysis.
MedBug combines a bedside sensor kit, the SENSE analysis models, and study-ready reporting so research teams can investigate sleep architecture and respiratory events across many nights — without attaching electrodes or wearable sensors to participants.
Research-stage platform for investigation and collaboration. Not a medical device.

The platform
From one night to many nights.
Measurable sleep and breathing outputs.
The MedBug SENSE models turn mattress-based overnight signals into sleep-stage, respiratory-event and physiology outputs for research workflows — designed for multi-night home and laboratory studies.
Overnight staging without wires
Mattress-based sensing turns body motion and cardiorespiratory signal into structured sleep-stage output for research workflows.

Can your mattress score every breathing pause?
Event-by-event classification of apnoeas, hypopnoeas and arousals across the night — with AHI reconstruction and severity summaries for research review.
Read more
Can one mattress signal show how hard you're breathing?
See how much air is moving and how hard the body is working to breathe — the physiology behind events, not just the event count.

Snoring, made visible
Audio-feature workflows map snore events and overnight acoustics alongside the rest of the physiological picture.

Vital signs, overnight
Heart-rate and respiratory-rate profiles derived from overnight piezo signals — continuous physiology without wearables.

MedBug 3 kit
Third-generation platform
Unobtrusive by design. Built for multi-night studies.
A mattress-based sensing approach brings physiological, acoustic and contextual signals together for multi-night sleep research in laboratory and home settings.
Evidence
Validation studies you can inspect.
Overnight staging vs PSG
Mattress-based sleep-stage output compared with polysomnography reference scoring.
- 67.5% epoch agreement
- 78.5% REM sensitivity
- −2.6 min Total sleep time bias
Event scoring and AHI
Apnoea, hypopnoea and related events scored overnight, then summarised as AHI against PSG.
- r = 0.94 model vs PSG AHI
- 7.3 /hr mean absolute error
- AUC 0.99 Central apnoea
Can one mattress signal show how hard you're breathing?
Continuous ventilation and respiratory-effort patterns beyond nightly event counts.
- r = 0.86 ventilation
- r = 0.70 respiratory effort
- Multi-night ventilation burden & effort instability
Can your mattress read your heartbeat?
Heart rate and breathing rate from under-mattress motion, checked against ECG and airflow.
- 0.74 bpm still HR MAE
- 3.41 bpm overnight HR MAE
- r = 0.78 beat-to-beat median
The science
From overnight sensing to reproducible analysis.
MedBug’s modular workflow moves from mattress sensing to quality control, model inference and human-readable reporting with a traceable run history for research teams.

How a MedBug study night becomes data.
On-mattress sensing for laboratory and home studies — without electrodes on the participant.
Capture
Record overnight BCG, static pressure and near-body temperature, plus multi-wavelength light, ambient temperature and air quality for study context — across continuous nights without wearable compliance burden.
Analyse
When out-of-bed is detected, overnight data uploads remotely and MedBug SENSE models run sleep staging, respiratory events and AHI, plus ventilation and effort physiology.
Report
Review study plots, tables and PDF outputs — including high-resolution, low-level model probabilities down to 1-second resolution for research use.
