Part 1 of this series provided an overview on using reflectometry for a pulse plethysmograph (PPG) waveform and described the physical and physiological principles at work. Much attention has been ...

Highly integrated, the new ultra-low power AS7058 supports sophisticated PPG applications and ECG and electrodermal activity measurements AS7058 AFE introduces body impedance measurement feature, to ...

Wearable health sensors such as photoplethysmography (PPG) wristbands, ECG patches and multi-modal biometric devices are typically developed and calibrated under controlled laboratory conditions.

Most biometric wearables today have moved to using an optical methodology called photoplethysmography (PPG), which shines light into the body and measures the light that bounces back – here is what ...
