PROBLEM

Poor Sleep is a driver of disease, not just a symptom

Sleep is increasingly recognized as a primary driver of systemic disease, not merely a consequence of it. Disrupted sleep dysregulates the biological processes that underpin cardiovascular, metabolic, and cognitive health, with measurable consequences at a population level.

01

20–30%

Of adults chronically affected by sleep loss or sleep disorders [1]

02

7 / 15

Leading causes of death linked to poor sleep [2,3]

03

30%

Higher dementia risk with persistent short sleep at ages 50, 60, and 70 [4]

04

€423B

Annual cost of sleep disorders in Europe (25% of all neurological disease costs)[1]

Sleep as modifiable target

The sleeping brain is active, measurable, and modifiable

During sleep, the brain enters a highly active and restorative state, measurable via EEG and modifiable through targeted intervention.

Solution

We built the end-to-end platform to modulate and measure the brain’s activity

Guided setup
Guided steps for correct application.
Remote communication
Connect with participants through the app.
Auditory stimulation functionality
Closed-loop auditory stimulation control.
Self-managed at-home use
Designed for independent home use.
Remote communication
Connect with participants through the app.

Built for Long-Term Use

Soft, lightweight, washable textile. Validated in studies of 18+ months. Available in sizes from children to adults — so every participant gets a perfect fit.

TOSOO AXORA

Closed-loop auditory stimulation

A non-invasive platform for sleep targeted neuromodulation

The AXORA headband captures medical-grade EEG and uses closed-loop algorithms to detect target sleep stages and deliver auditory stimuli via built-in headphones. This enables targeted modulation of sleep features, such as slow-wave activity.

Wavescope manages your study end to end: participant and device management, double-blinded sham-controlled study setup, automated data quality checks, and full raw EEG data access, all in one place.

Complete system

Headband, Patient App, Wavescope

Long-term wear

Validated for 18+ months of continuous home use

Stimulation protocol

At-home Sleep Monitoring

AXORA EEG

At-home Sleep Monitoring

At-Home EEG Monitoring for longitudinal studies

The AXORA EEG headband records medical-grade EEG continuously at home, giving your study access to a full range of sleep endpoints — from sleep staging and continuity to microstructure measures like slow-wave power and sleep spindle density.

Precision wet-electrodes and a mobile amplifier ensure signal quality on par with PSG, in a form factor participants actually keep wearing.

Cumulative safety record

“SleepLoop® [predecessor of AXORA] is currently the only portable PLAS-capable home-use device explicitly designed for research purposes. Its biggest advantages are full methodological transparency, high configurability, and full availability of raw data.” [13]

Zeller et al. (2023)

Journal of Sleep Research

“The first at-home EEG we’ve run a longitudinal study with that didn’t fall apart by week four.”
