Respiratory and heart rate monitoring using an FBG 3D-printed wearable system

This work proposes a 3D-printed sensor based on fiber Bragg grating (FBG) technology for respiratory rate (RR) and heart rate (HR) monitoring. Each sensor is composed of a single FBG fully encapsulated into a 3D-printable Flexible, during the printing process. Sensors with different material thicknesses and infill densities were tested. The sensor with the best metrological properties was selected and preliminary assessed in terms of capability of monitoring RR and HR on three users. Preliminary results proved that the developed sensor can be a valuable easy-to-fabricate solution, with high reproducibility and high strain sensitivity to chest wall deformations due to breathing and heart beating.

Automated summary

This study proposes a 3D-printed sensor based on fiber Bragg grating (FBG) technology for monitoring respiratory rate (RR) and heart rate (HR). The selected sensor demonstrates high reproducibility and sensitivity to chest wall deformations caused by breathing and heartbeats, making it a valuable solution for easy fabrication.
