A Statistical Metrology Approach to Compare the Quality of Optical Pulse Wave Signals

Biometric metrology is becoming increasingly important as the wearable application specific biosensors are becoming capable of generating accurate raw signals representing certain vital states.A comparative Biosignal Metrology method has been worked out (patent pending ID: P1900302) to answer questions arising from a biosensor and biosignal testing measurement science perspective.In this specific work two high quality optical solutions (Analog Devices’ : ADPD107 (EVAL-HCRWATCH) and ADPD188GGZ) were compared to analyze the deep data level similarities or differences between the photoplethysmography (PPG) raw biomedical signals generated by the two individual systems.Based on the results we can conclude that the quality of the PPG signal recorded by the new ADPD188GGZ integrated optical module reaches the same performance level as the ADPD107 discrete module according to the newly established Biosignal Metrology Standards.
