Fibion Circadian

Accurate and easy measurement of circadian sleep-wake-activity cycles 


Tiny sensor measures the body's position and movement minute by minute, around the clock.

Cloud portal

Automatic data transfer via smart phone to secure cloud.


Easy to interpret sleep-wake-activity cycle reports to support evidence-based decision making.

How it works?

Fibion Circadian consists of a tiny sensor that is attached to the middle of the back with a custom-made patch. The sensor automatically sends data about the citizen's activity to an online portal.

The sensor measures the body's position and movement minute by minute, around the clock. The collected data is stored and analyzed in our online portal, where professionals can see when the citizen is lying, standing / walking, restless or relaxed. 

Our circadian rhythm schedule can be used as a supplement to or replacement for your normal restlessness schedules and to assess the citizen's general well-being. Furthermore, you can use it as a basis for any new decisions of care measures. 

Why use Fibion Circadian?

Provides an objective and complete picture of the citizen's circadian rhythm.

Reveals sleep disorders, night walking, restlessness, hyperactivity or inactivity.

Allows for easy sharing of the results with colleagues, doctors, psychologists or relatives.

Measures and documents the effect of new care measures.

Importance of sleep-wake rhythm

A disturbed sleep-wake circadian rhythm can lead to serious sleeping problems. Research continues to uncover details about circadian rhythms, but evidence has connected them to metabolism and weight through the regulation of blood sugar and cholesterol. Circadian rhythms influence mental health as well, including the risk of psychiatric illnesses like bipolar disorder and depressionas well as the potential for neurodegenerative diseases like dementia.


The one area where actigraphy can be used for clinical diagnosis is in the evaluation of circadian rhythm disorders. Actigraphy has been shown to be very good for identifying rhythms... Actigraphy therefore would be particularly good for aiding in the diagnosis of delayed or advanced sleep phase syndrome, non-24-hour-sleep syndrome and in the evaluation of sleep disturbances in shift workers."
