Characteristics of the BioTel 3DNX™ accelerometer instrument   

The 3DNX™ accelerometer instrument monitors physical activity in free-living humans using tri-axial accelerometer technology. Worn in a pouch on a belt around the waist, the instrument registers accelerations and decelerations caused by movement of the body.
As specific characteristics the instrument:                                                  

• Offers the advantages of a tri-axial accelerometer 
• Monitors body movement in 3 dimensions.
• Measures frequency and intensity of movement.
• Offers flexible settings for sample interval (epoch) and filters.
• Non invasive, no wires or uncomfortable attachments.
• Supports ongoing monitoring in free-living conditions.
• Is worn 24/7 (10 to 700 days without data download or battery charge).
• Enables prediction of energy expenditure and physical activity indices (e.g. PAL, MET).
• Provides a linear relationship with walking and running at speeds up to 20 km/h.
• Ensures high accuracy & reliability proven both in the laboratory and in rough environments (i.e. military & first responder studies).
• Produces output available for import in personalized program & internet-technology.

These qualities can also be specified for specific usergroups and as differentiator to the existing competition.

Research specific qualities:

• 3DNX is not just an of the shelf product, it can be adjusted to the specific needs of a usergroup.
• 3DNX can provide algorithm processed data or raw data for analysis in bespoke customer software.
• 3DNX can be used for realtime monitoring in laboratory environments.
• 3DNX has the possibility to select sample interval and to adjust filtering to meet the project needs.

Rehabilitation, physiotherapist and sports physiologist specific qualities:

• 3DNX enables analysis of the pattern of body motion through the 3 dimensional registration.
• 3DNX offers the combination of clinical accuracy and robustness of the instrument which supports use in free living environments.

Army and 1st responder specific qualities:

• 3DNX offers a very robust instrument that resists extreme circumstances.
• 3DNX can be used for accurate registration during longer periods like training programmes in larger populations.
