Abstract
This paper presents a technique for cardiac rate and blood pressure monitoring using fiber Bragg grating sensors. A wearable FBG-based sensing wristband with adjustable air bag was fabricated. After pressuring the air bag, the FBG sensors monitored cardiac rate by detecting pulse vibrations in the wrist area. Blood pressure was determined based on the pulse wave signals. The sensing wristband can achieve real time cardiovascular monitoring with a high resolution of
0.02 ms. Machine learning is used for cardiovascular diseases diagnosis. The experimental results show that compared with other traditional sensing devices, our sensing wristband is more compact, has a higher resolution and a faster response time.
