  • You need real brain data from real bedrooms

    Your study deserves real EEG, accurately measuring your subjects real sleep in their own bed, with a device so comfortable they wear it night after night.

  • Wrist trackers estimate, not measure

    Actigraphy and finger worn wearables derive only sleep stages from heart rate and motion. No sleep spindles, no K complexes, no raw signal access, and not accurate

  • In lab PSG has limitations

    Gold-standard polysomnography costs $300+ per night, requires a lab visit, and captures a single night of data in an artificial environment. It doesn't scale.

Independently validated

Sleep staging you can trust

  • 0.76 Cohen's Kappa
  • 88–96% Accuracy across all stages
  • 79–92% Sensitivity per stage
  • 90–99% Specificity per stage

Validated against Level 1 polysomnography by the Canadian Sleep Research Consortium (Lanthier et al., 2025). Published in SLEEP Advances, Oxford Academic. 56 adults (20–71 years), including participants with sleep-related breathing disorders. AASM-aligned automated staging across Wake, N1, N2, N3, and REM.

Sleep architecture

Macro and micro events, every night

Muse captures the full spectrum of sleep architecture. Automated scoring classifies Wake, N1, N2, N3, and REM. Micro events — sleep spindles, K complexes, and slow waves — are detected and quantified.

Created in partnership with the Canadian Sleep Research Consortium. Suitable for adult and pediatric populations.

The first wearable to combine EEG, fNIRS, PPG, SpO2, and motion in a single fabric headband. No other device at this price point offers this multimodal capability.

CE, FCC & UL certified. Soft antibacterial fabric. No adhesive. Compatible with Muse 2 and Muse S for multi-device studies.

  • 4ch EEG256 Hz dry
  • fNIRSL+R PFC
  • PPG+SpO264 Hz
  • Accel3-axis 52Hz
  • +4 auxEEG/EOG/EMG
  • 41g10hr battery

Interventional capability

Closed-loop stimulation
for sleep intervention studies

Most portable sleep EEG devices are measurement-only. Muse is different. Programmable closed-loop protocols let you run interventional studies — not just observational ones.

Available protocols: Targeted memory reactivation (TMR), auditory deep sleep stimulation (EEG-timed pink noise cues during slow-wave sleep), and custom stimulation protocols designed with your research team. Built-in safeguards automatically pause stimulation if signs of arousal are detected.

Frequently asked questions

Frequently asked questions

Has Muse's sleep staging been validated against polysomnography (PSG)?

Yes. Muse's sleep staging has been independently validated against polysomnography, the clinical gold standard. The Lanthier et al. (2025) study published in SLEEP Advances reported a Cohen's kappa of 0.76 (expert scoring agreement in 0.75) and per-stage accuracy of 88–96%, which is comparable to inter-rater agreement between expert PSG scorers. This validation was conducted independently and is not manufacturer-funded.

The Muse’s sleep scoring is based on EEG alone, and is considerably more accurate than sleep wearables on the finger or wrist (actigraphy)

What EEG data format does Muse output, and how do I access it?

Our research tools output raw EEG, Optics (PPG / fNIRS), and accelerometer data via OSC and LSL, and can record files in CSV and EDF. Muse’s EEG is 256hz. Muse’s sleep research tools also provide PSG level sleep scoring according to ASSM guidelines.

The consumer Muse app cannot provide this data, you need to contact us to gain access to our research tools.

What is the sampling rate and signal quality of Muse EEG?

Muse samples EEG at 256Hz, which is more than sufficient for research-grade sleep staging, event-related potential (ERP) studies, and spectral analysis. The device uses dry electrodes with active noise cancellation, and independent validation studies have confirmed signal quality comparable to clinical-grade ambulatory EEG systems. Muse 2 and Muse S Athena also include PPG and accelerometry in a single wearable device, and Muse S Athena can provide SpO2 in our research tools.

Can I get raw EEG data from Muse?

Yes. Muse provides high-quality raw EEG data at 256Hz through dedicated research software tools available on both desktop and mobile. The data is unprocessed and suitable for academic research. If you are using the Athena device you also get raw optical data for FNIRS analysis. For data privacy and security, you cannot get raw data directly from the consumer version of the Muse app, you need a license to use our HIPPA compliant, IRB approved secure research tools.
