Abstract

In this paper, we present an optical fiber based approach to accurately evaluate the respiratory capacity of individuals through spirometry. The proposed system converts the air flow rate into strain variations in an optical fiber, which will modulate the spectral response of a Fabry-Perot interferometer (FPI) micro-cavity, created in the fiber core. Simulation studies were performed to verify the proposed theoretical approach. Additionally, preliminary results concerning the study of the system's reliability are also presented, which confirm the suitability of using FPI sensors for the evaluation of spirometry parameters. The simulation and implementation results showcase the accuracy of the measurements performed by the proposed solution, confirming its appropriateness to be used as a smart low-cost eHealth spirometer. This is the first time such FPI approach is used with this purpose.
