Fibion G2

Fibion is the only research device that has been validated to track accurately sitting, standing, physical activity types and energy expenditure. The tracked physical activity types are slow walking, brisk walking, cycling, and high-intensity activity.

Future-Proof Tri-Axial Raw Data

In addition to automatically produced result variables and participant reports, Fibion G2 records also raw high-resolution tri-axial acceleration data. Fibion G2 data is future-proof as it can be reprocessed indefinitely as new analytical methods and algorithms are developed.

Unmatched Precision

With best-in-class 16-bit resolution, the G2 captures every subtle movement with 64 times the detail of standard devices. From precise posture shifts to nuanced activity changes, G2’s unmatched precision delivers insights that go beyond traditional tracking.

Event Marker Button

The Fibion G2’s event marker button allows participants to log key moments with a simple press, adding valuable context to physical activity and sleep data. This unique feature enriches data with precise, participant-driven details, offering researchers a deeper understanding of behavior patterns.

Discover the Power of Fibion Reports

In addition to scientific accuracy, Fibion provides automatically produced and easy-to-understand reports for research participants.

Thigh Strap Wearing Options

Advanced analysis algorithms and positioning of the device on the thigh instead of the waist or wrist gives considerably more accurate results especially related to sedentary behaviours and low-intensity physical activities

Versatile Wearing Options

Fibion G2 can be worn on the thigh for accurate sedentary behaviour and physical activity measurements; on the chest for sleep and sleep position metrics, or on the wrist as a classic actigraphy device.

Advantages

Fibion offers significant advantages over other research solutions, providing accurate measurements of sitting, standing, and various activity intensities.
