New design and improvements of an MR-compatible respiratory fiber-optic sensor

Abstract

The article describes a modification of the fiber-optic sensor based on a Bragg grating, which is implemented in oxygen glasses, which are commonly used in real medical practice. This type of experimental fiber-optic sensor can be used to monitor the respiratory activity of the human body over time. Modifications primarily consist of the design improvement of the Bragg grating implementation itself in using conventional oxygen glasses for better transfer of measured parameters to the Bragg grating itself. The practical part also describes the experimental verification of the functionality and the subsequent evaluation of the measured data. The experimental measurement was carried out on a group of 5 volunteers in laboratory conditions.
