Why the study?
Advancement of age and increased awareness of public health have heightened the demand for continuous vital sign monitoring devices.
Does a wrist-worn fiber Bragg grating (FBG) sensor provide pulse wave signals comparable to SDPTG for estimating vascular age and arteriosclerosis?
Does a wrist-worn fiber Bragg grating (FBG) sensor provide pulse wave signals comparable to SDPTG for estimating vascular age and arteriosclerosis?
A novel noninvasive FBG sensor can capture pulse wave signals similar to SDPTG, demonstrating feasibility for continuous monitoring of vascular age and arteriosclerosis.
May support wearable FBG for continuous vascular monitoring; leaves open validation for clinical arteriosclerosis assessment.
The advancement of age and the increased awareness of public health have resulted in increased demand for continuous vital sign monitoring devices. Therefore, we developed a noninvasive vital sign measurement device without physical resistance to the user using a fiber Bragg grating (FBG) sensor. The FBG sensor was fixed on the wrist, and a pulse wave signal was obtained. Additionally, we focused on the similarity between this pulse wave signal and the second derivative of the plethysmogram (SDPTG). Classifying this signal, we found that its shape changed according to the age and blood pressure. We found that the change in the shape of the pulse wave signal and the SDPTG have the same tendency. Therefore, it is feasible to estimate the vascular age and arteriosclerosis with the signal obtained by an FBG sensor. On the basis of these results, the FBG sensor system can measure multiple vital signs and monitor health more comprehensively.
