Signal robustness dependency on sensor contact force in a novel photoplethysmography-based multi-purpose sensing device

A new photoplethysmography-based device called the Multiphotodiode Array (MPA) was validated to successfully measure the PWV in the vasculature of the distal phalanx of healthy subjects. It comprises an array of photodiodes and an array of opposing LEDs to detect blood volume changes due to the passing pressure pulse wave in the vasculature of...
