Tracking oxygen saturation with Biostrap

Long term oxygen saturation monitoring

Nov. 15, 2017 - Willem L. Middelkoop

Most wearables (smartwatches, fitness trackers, etc.) use very basic sensors to capture heart rate. Their signal is binary: just counting beats.

Heart rate variability (HRV) as measured and explained by Biostrap

Unboxing Biostrap: it comes well packed in a nice box.

The box contains three straps, charging cable, charger and two sensors

On the bottom you can see the two red LED's and the PPG sensor. Just like the Swatch Sistem51 movement this is hidden when worn on wrist

Biostrap it's pretty much just like a Swatch, light on the wrist because of it's material: rubber and plastic.
