Abstract
A simple, portable, and low-cost system for noninvasive measurement of vital parameters, based on two sensors conveniently combined in a unique compact-in-size and low-power structure, has been presented and characterized in this work. The proposed solution allows both sensors to fit in a small structure, in order to be applied on the earlobe (or analogue body part of a person) in a clip-like fashion, making it suitable for portable and battery-operated systems. The two involved sensors are as follows: a photoplethysmographic (PPG) sensor, used to optically measure the change in volume of blood in the arteries, thus to acquire information about heart beating, and a sensor composed by two electrodes, used to perform an impedance measurement, thus to monitor the dielectric properties of biological tissues and fluids, like blood flow.
