Abstract :
This paper describes the development of an optophysiological model of a finger in conjunction with a ring-type photoplethysmography device (the ring sensor). It describes the photoplethysmographic effects due to the relative displacement and rotation of a finger to a ring-type optoelectric device that monitors the arterial pulsation noninvasively and continuously. Numerical simulations and experiments were conducted to verify and evaluate this model
