![]() This FBG-based system can provide high accurate measurement, and the key characteristic parameters can be then extracted from the raw signals for clinical applications. The FBG sensor can achieve the sensitivity of 8.236Â nm/N, which is comparable to a commonly used electrical sensor. ![]() The proposed optical sensing system is featured as high sensitivity and immunity to electromagnetic interference for multilocation radial artery pulse waveform measurement. As a three-dimensional cylinder, the radial artery needs to be examined from different locations to achieve optimal pulse waveform for estimation and diagnosis. High fidelity radial artery pulse waveform has been investigated in clinical studies for estimating central aortic pressure, which is proved to be predictors of cardiovascular diseases. Pulse waveform analysis is a diagnostic tool for clinical examination and disease diagnosis. In this paper, we report the design and experimental validation of a novel optical sensor for radial artery pulse measurement based on fiber Bragg grating (FBG) and lever amplification mechanism. ![]() ![]() Jia, Dagong Chao, Jing Li, Shuai Zhang, Hongxia Yan, Yingzhan Liu, Tiegen Sun, Ye ![]() A Fiber Bragg Grating Sensor for Radial Artery Pulse Waveform Measurement. ![]()
