NIRSleep is developing an easy-to-use wearable neuroimaging platform to calculate sleep indices by measuring cerebral oxygenation. Our technology and design will produce higher quality data and more actionable insights than consumer wearables but won’t disrupt the sleeper with bulky or wired multi-component systems like current sleep-measurement tools. NIRSleep is easy to use for multi-night tests and may capture behavioral conditions such as insomnia. Interestingly, the platform could be used during wake to investigate cognitive function, or cerebral hypoxia. NIRSleep is rugged, waterproof, easily integrated into headgear like skullcaps and helmets, and can either stream or store data securely on board.
