Understanding the respiratory stress band sensor on the Versatile Bio
What it measures:
The respiratory stress band detects a participant breathing via an elastic band worn around the chest.
Sports, rehabilitation, kinesiology, psychology, biomechanics, neuromarketing, etc.
How to use:
The sensor band is placed around the participant's chest and under the arms and tightened enough to be snug. We recommend taping the cables to the participant's body in order to avoid movement artifacts.
How to clean:
The sensor can be cleaned with cotton and alcohol or a 2% diluted hospital cleaning solution. The Velcro can be washed with household detergent, then air dried.
Do not immerse the sensor or cables in liquid. Autoclave is not recommended.
Connector on Versatile Bio:
Right-click on wave view in Bitbrain Device Viewer to view data-visualization filter settings.
Under "Notch-Filter" we recommend setting this to the preset matching your country's AC frequency (presets exist for USA/Japan at 60 Hz, and Europe at 50 Hz).
Under "Other Filter" click "enabled"
Set filter type to "Bandpass"
Set High (Hz) to 5 Hz
Set Low (Hz) to 0.1 Hz
Type is "Butterworth"
Order set to 4
Sensitivity: 2-30 µV/mm
Output Bandwidth: 0.5 Hz to 12 Hz
Output data is reported in microvolts and is relative to the expansion and contraction of the band during inhalation and exhalation.
Absolute voltage amplitude and signal strength can vary based on sensor placement and size of the participant.
