The innovative wearable medical device for objective sleep measurements.

Currently, there are no clinically validated option between the gold-standard polysomnography and the actimeter available for researchers, clinicians and patients.

That is why PPRS, a French medical device manufacturer, has developed the first automatic ambulatory solution that simplifies sleep scoring.

Somno-Art, a CE marked medical device, is composed of an electronic armband that captures physiological data and a stand-alone software to generate medical grade sleep reports, with results similar to the polysomnography.

Designed for researchers

Somno-Art is the perfect tool for researchers looking to use the sleep biomarker in their studies, either for academic or drug-development related purposes, in an easy and robust way.

The solution allows to do recordings on large cohorts, with minimal discomfort for patients, hence with a high acceptance rate.

Offering Clinical Data to Clinicians and Patients

Today, between 10% and 20% of the population encounters sleep disturbances which can be the direct consequence of sleep disorders (insomnia, sleep apnea, narcolepsy...), linked to other diseases (cardiovascular or metabolic disorders such as diabetes, anxiety or depressive disorders...) but also due to behavioral, professional or environmental factors (stress, shift work, exposure to screens, ambient temperature...). These disorders, which are complex to diagnose, are recognized as a major health problem.

With Somno-Art, physicians have now the ability to quickly diagnose the quality of sleep of their patients, to continuously monitor their sleep, and to understand the possible adverse-effects of prescribed therapies. Doctors can better assist their patients to improve their sleep and quality of life.

Hospitals will be able to free up beds usually reserved for Polysomnography (PSG) testing and facilitate remote and long-term monitoring of patient sleep.


An automatic sleep scoring solution

Heart rate and body motor activity can be used to discriminate between wake and sleep as well as to distinguish all sleep stages and their transitions. These two physiological measures are used by the software to automatically score the hypnogram.


A fully automated, wearable device allows a user-friendly recording of sleep and vigilance states, independently of the location of the user (home, clinic, travel).

With results similar to PSG

Several studies have been conducted recording with PSG, heart rate and body motility devices on healthy volunteers and patients with sleep or CNS disorders. Sleep architecture and continuity results obtained through Somno-Art were similar to those obtained by visual scoring of simultaneously recorded PSG.


The armband allows robust and precise data acquisitions of heartbeats and body movement for sleep analysis. We are working on a new version that extend the data collection during the 24-hour period.
