All with one device

Validated sitting, standing, physical activity types, energy expenditure, and easy-to-understand reports for the research participants

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.

Fibion has also been shown to be valid categorizing physical activity into light (LPA), moderate (MPA), and vigorous (VPA) intensity physical activity.

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.

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


Fibion provides considerable advantages compared to other research solutions as it can accurately measure both sitting, standing and different intensities of activity.
