Arterial simulators are pivotal in cardiovascular system research, enabling in vitro studies of hemodynamic parameters such as pulse wave velocity (PWV), a key marker of arterial stiffness. This work presents the design, fabrication, and preliminary characterization of a novel flexible sensor based on fiber Bragg grating (FBG) technology for capturing real-time diameter variations in compliant arterial models. The sensor features a ring-shaped configuration to ensure conformability and mechanical compatibility with vascular phantoms. The proposed sensing approach addresses limitations of traditional electrical sensors by offering high sensitivity, minimal mechanical interference, and robust integration. Preliminary metrological evaluations suggest the FBG sensor's suitability to detect and appreciate minimum and maximum strains of 5 % and 30 %, respectively, for the intended application, paving the way for high-fidelity, non-invasive PWV measurements in controlled experimental setups.

Abstract
Arterial simulators are pivotal in cardiovascular system research, enabling in vitro studies of hemodynamic parameters such as pulse wave velocity (PWV), a key marker of arterial stiffness. This work presents the design, fabrication, and preliminary characterization of a novel flexible sensor based on fiber Bragg grating (FBG) technology for capturing real-time diameter variations in compliant arterial models. The sensor features a ring-shaped configuration to ensure conformability and mechanical compatibility with vascular phantoms. The proposed sensing approach addresses limitations of traditional electrical sensors by offering high sensitivity, minimal mechanical interference, and robust integration. Preliminary metrological evaluations suggest the FBG sensor's suitability to detect and appreciate minimum and maximum strains of 5 % and 30 %, respectively, for the intended application, paving the way for high-fidelity, non-invasive PWV measurements in controlled experimental setups.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
