Abstract
We report progresses in the development of a processing pipeline intended for photoplethysmogram (PPG) based on the use of silicon photomultipliers (SiPMs) detectors. Such probe sensors offer relevant advantages in terms of single-photon sensitivity and high internal gain for relatively low reverse bias. Along with the SiPMs detectors, an ad-hoc processing pipeline, we developed, offers advantages e.g. in order to correct signal distortions. The processing pipeline is composed by the PPG raw signal filter, consisting of a FIR pass-band scheme (low-pass filter plus high-pass ones), the PPG pattern recognition system, and completed with the medical indicators detection system and the indicators extraction.
