Advanced stress levels with Biostrap

Long term stress levels 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.

The Biostrap PPG sensor is about as thick as a watch

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

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 on the wrist - now you see me...

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