“…Although various studies have explored the use of 3D printing and fiber optic sensors for diverse applications, this publication uniquely focuses on utilizing 3D-printed FBG sensors for vital sign monitoring. Previous works [38] and [39] have explored the measurement of heart and breathing rates with 3D-printed encapsulated Bragg gratings, while [40] employs PLA filament for FBG sensor encapsulation, unlike using the ABS filament described in this article, which has different mechanical properties that affect sensor performance. Additionally, such FBG sensors have been applied in biomedical devices such as spirometers [41] and respiratory activity sensors embedded in oxygen masks [42], offering advantages in MRI environments by reducing motion artifacts.…”

Currently, the use of fiber-optic Bragg gratings in biomedical applications, especially in the field of magnetic resonance imaging (MRI), is becoming popular. In these applications, the fiber Bragg grating (FBG) encapsulation plays a crucial role in terms of the accuracy and reproducibility of the measurements. This paper describes in detail the fabrication method of a prototype FBG sensor, which is realized by encapsulating a Bragg grating between two layers of the MR-compatible material Acrylonitrile Butadiene Styrene (ABS) by 3D printing. The sensor thus created, implemented, for example, on the chest of a human body, enables monitoring of the vital functions of the human body. The paper describes the complete procedure for the creation of the prototype sensor, including strain and temperature dependence, as well as results of long-term experimental measurements against the conventional electrocardiography (ECG) standard. Results based on the objective Bland-Altman (B-A) method confirm that the implemented sensor can be used for reliable monitoring of cardiac activity (>95% based on B-A). Taking into account the single fiber optic cable, its simple implementation, its small size and weight < 5g, the presented sensor represents an interesting alternative to conventional ECG.INDEX TERMS fibre Bragg grating, 3D printing, vital sign monitoring, heart rate, MR-compatible.

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.
