What is the technology behind FibriCheck?

FibriCheck uses the smartphone camera (and flashlight) to capture a PPG signal. The PPG signal measures the light absorption in the finger. 

Since ECG is most commonly known, a validation study has been performed. This study shows that ECG vs PPG beat-to-beat interval has a correlation of 99,3% .
