Remote patient monitoring is flourishing in the sleep field, and devices that can objectively measure sleep with high ecological validity are highly desired by practicing clinicians. However, Home Sleep Tests (HSTs) cost sleep clinics far more than they should, and they’re uncomfortable and overcomplicated for patients.  

NIRSleep is developing a small wearable noninvasive brain imaging system to serve this need, and to support remote populations by increasing the accessibility, availability, and acceptability of critical sleep medicine.

NIRSleep is designed to calculate sleep indices such as sleep onset latency, wake after sleep onset, total sleep time, apnea/hypoxia index, and sleep efficiency.

The NIRSleep platform delivers the combination of

• greater clinical relevance over peripheral oximetry available on most commercial wearables with

• less obtrusiveness and complexity than clinical polysomnography (PSG). Our clinical work on the NIRSleep platform has already demonstrated the ability to identify sleep behavior in subjects in supervised clinical settings.
