- It is most important to wear Skyn on the underside of the wrist, about 1 inch away from the joint between your hand and wrist (opposite of where a watch would go).
- This is critical because the underside of the wrist has a significantly larger number of arteries and veins, which translates into a stronger TAC signal.
- If Skyn is worn on the top of the wrist, the TAC signal will be weaker, and the data collected will have more noise.
- The second most important thing is the tightness of the band.
- The Skyn sensor should be snug to the user’s wrist, and should not lose direct contact with the user’s skin at anytime.
- If worn tight enough, the sensor will likely leave a light imprint on the user’s wrist, this is okay (just make sure the band is not uncomfortable).
- Another point to consider is motion - the more the Skyn sensor jiggles on the wrist, the more noisy the data will be. Some of the cleanest data collection sessions actually occur when a user is working or idle at a desk, as they are not moving around and their environment is not changing.
- Lastly, it’s best practice to wear Skyn on the user’s non-dominant hand. This is helpful in cases where the user may be holding an alcoholic drink, or using more sanitizer on the dominant hand.
