An FBG‐based optical pressure sensor for the measurement of radial artery pulse pressure

One of the diagnostic tool for clinical evaluation and disease diagnosis is a pulse waveform analysis. High fidelity radial artery pulse waveforms have been investigated in clinical research to compute central aortic pressure, which has been demonstrated to be predictive of cardiovascular diseases. The radial artery must be inspected from several angles in order to obtain the best pulse waveform for estimate and diagnosis. In this study, we present the design and experimental testing of an optical sensor based on Fiber Bragg Gratings (FBG). A 3D printed device along with the FBG is used to measure the radial artery pulses. The proposed sensor is used for the purpose of quantifying the radial artery pulse waveform across major pulse position point. The suggested optical sensing system can measure the pulse signal with good accuracy. The main characteristic parameters of the pulse can then be retrieved from the processed signal for their use in clinical applications. By conducting experiments under the direction of medical experts, the pulse signals are measured. In order to experimentally validate the sensor, we used it to detect the pulse waveforms at Guan position of the wrist's radial artery in accordance with the diagnostic standards. The findings show that combining optical technologies for physiological monitoring and radial artery pulse waveform monitoring using FBG in clinical applications are highly feasible. The design and experimental testing of an optical sensor based on Fiber Bragg Gratings (FBG) is presented in this paper. An FBG is used to measure the radial artery pulses using a 3D printed instrument. The intended sensor is used to measure the pulse waveform of the radial artery across the principal pulse location point. The pulse signal is accurately measured by the optical sensing device. After the signal has been analyzed, the primary pulse characteristic parameters can be extracted for use in therapeutic applications. The pulse signals measured by experiments are carried out under the supervision of medical professionals. We employed the sensor to detect the pulse waveforms at Guan position of the wrist's radial artery in line with the diagnostic requirements in order to experimentally validate it. The results demonstrate how highly feasible the proposed technique to combine optical technologies for physiological monitoring with FBG‐based radial artery pulse waveform monitoring in clinical applications.
