Every Heartbeat, Every Breath, Every Shift Captured While They Sleep
Nucu's Ambient Bio-signal Sleep Sensor uses fluid-coupled ballistocardiography (patent pending) to pick up three physiological signals at once: high-resolution heartbeats, respiratory undulation, and micromovements. No wearable touches your child's skin the sensor reads these signals straight through the mattress, turning raw biological noise into a clear picture of how your child actually sleeps.
It's not just about how long they
sleep — it's about what's
happening around them.
Nucu also reads the bedroom itself — light, noise, temperature, and humidity — the environmental context that wrist-worn trackers can't see.

Designed with intention
Nucu Co-founder Juha Hannula and the team designed Nucu to be calm by default: contact-free sensing, privacy-first choices, and insights that help without adding noise.
During sleep, the brain processes new information, strengthens memory connections, and supports cognitive development.
Quality sleep supports the systems responsible for mood, stress response, and emotional resilience throughout the day.
Sleep plays an important role in physical growth, energy restoration, metabolic health and healthy development.
Consistent sleep routines help children stay focused, engaged, and ready to learn.
Nucu reveals patterns behind sleep quality — helping parents understand what their child needs to build healthier habits.
