In 2017, four UC Berkeley neuroscientists set out on a mission to transform how we sleep. 8 years, 1000s of nights of data, and a peer-reviewed study later, Cernosleep was born — a first-of-its-kind sleep wearable that strengthens your brain's natural sleep ability, night after night.

Cernosleep uses lab-grade EEG+ sensors to read and track your brain’s real-time sleep activity — giving our AI engine the raw data it needs to understand how your brain likes to sleep and build your personalized neurostimulation program.
Each night, Cernosleep delivers gentle, AI-personalized electrical waves (tACS) that mirror and enhance your brain’s optimal sleep signals to create an effortless journey into deeper, more efficient rest.
The way your brain likes to sleep changes night to night, and over time. After 21 sessions, Cernosleep SmartSleep AI â„¢ is fully personalized and primed with all the data it needs to dynamically evolve your stimulation for lifetime adaptation.
Dynamic AI/ML-Powered Personalization
Cernosleep improves sleep quality by delivering gentle electrical signals personalized to your brain. These gentle signals nudge your brainwaves into their optimal rhythms for deeper, more restorative rest.
Our Breakthrough
After testing auditory, tactile, and visual stimulation for better sleep, Cernosleep’s science team found our breakthrough:Â
Carefully timed, gentle electrical pulses, personalized to your brain's sleep signals. Amazingly, our team found that this approach didn’t just help people fall asleep faster... It actively strengthened deep sleep brainwaves, reduced wake-ups by 33%, and increased total sleep time by nearly 30 minutes on average.
