Sleep Neurotechnology

Engineering Sleep
for Better Minds.

Most sleep devices observe bad sleep. They tell you what already went wrong. BrainAmu is designed to intervene — before sleep breaks.

From measuring sleep
to protecting it.

For a decade, wearables have perfected the art of describing the night. BrainAmu starts from a different question: what if a device could read the earliest signs of instability — and act, gently, in real time, to keep sleep intact?

The world today

Devices that watch sleep fall apart.

Trackers, rings and watches produce beautiful reports of a night that has already happened. The damage is recorded, not prevented.

The BrainAmu thesis

A device that stabilizes sleep as it happens.

Sleep fragmentation may not only be a symptom — it may be an actionable physiological instability. The goal: detect it early, and respond before the night unravels.
The closed loop

Sense. Predict. Stabilize.

BrainAmu is conceived as a wearable closed-loop system — a continuous conversation between the body and an intelligent device, running quietly through the entire night.

01

Multimodal sensing

Comfortable, wearable-grade biosignals captured continuously overnight — the physiological texture of sleep, read in real time.

02

AI prediction

Models designed to recognize the signature of fragmentation before it surfaces — anticipating instability rather than reporting it.

03

Real-time thermal modulation

A gentle, localized, closed-loop response engineered to support sleep continuity — the intervention layer no tracker has.

Where it matters most

Built around the people
whose nights break.

BrainAmu's research focus begins where sleep fragmentation carries the highest cost — for cognition, memory, and quality of life.

/ 01

Narcolepsy

Unstable REM and fragmented nights — the disorder BrainAmu's founder lives with, and the first reason it exists.

/ 02

Alzheimer's & cognitive decline

Disrupted sleep and neurodegeneration are deeply intertwined. A frontier worth protecting.

/ 03

Chronic fragmentation

Nights silently broken into pieces, eroding recovery without ever feeling like insomnia.

/ 04

Insomnia

Difficulty maintaining continuous, restorative sleep through the night.

/ 05

Aging & unstable sleep

Older adults, and care settings, where stable sleep is fragile and consequential.

One ecosystem, two worlds

The hardware that protects sleep.
The community that explores it.

BrainAmu is the serious neurotechnology platform. DreamAmu is its consumer and community layer — where people record, understand and learn to navigate their dreams.

The founder
Alex Champavert FOUNDER · BRAINAMU

A sleep researcher who lives the problem he is solving.

Alex Champavert is himself narcoleptic. BrainAmu did not start as a business plan — it started with fragmented nights, and a refusal to accept that sleep technology should only describe the damage rather than prevent it.

That lived experience led him into the labs that study sleep at the highest level. He has worked alongside Dr Patricia Franco at CRNL / Hôpital Femme-Mère-Enfant in Lyon on pediatric sleep, sleepiness and narcolepsy — and with Pr Isabelle Arnulf's Dream Team at the ICM / Pitié-Salpêtrière in Paris on REM sleep, dreaming and lucid dreaming, two of the most respected names in European sleep science.

Today he also works in front-line memory care, where the cost of broken sleep on cognition is impossible to ignore.

Our promise

Ambitious about the future. Honest about today.

We will not sell certainty we do not have. BrainAmu is a research-stage project, and we believe that transparency is the credibility. Here is exactly where the science stands.

EstablishedSleep fragmentation is a real and meaningful problem — strongly linked to cognition, memory, narcolepsy and neurodegeneration. This is well documented.
PlausibleThermoregulation is intimately tied to sleep regulation. Localized thermal modulation as a lever on sleep stability is a scientifically reasonable hypothesis grounded in known physiology.
To be testedWhether a wearable can intervene fast enough and safely enough to influence fragmentation in real time. This is the core question our R&D is built to answer.
Our scope todayBrainAmu is a wellness and research-oriented project that supports sleep continuity and understanding. Rigorous clinical validation is a deliberate, staged path for the future.
