Pulse wave velocity (PWV) is considered the gold standard for assessing arterial stiffness and recently, it has been recognized as an important indicator in the diagnosis and treatment of cardiovascular disease. Currently, there are commercial devices capable of measuring PWV, however, significant investments are required and some devices requires specialized training for their correct use. Conventional pressure-sensing devices are mainly based on piezoresistive, piezoelectric and capacitive sensors. Recent investigations, however, show that pressure transducer using magnetic sensors based on the giant Magnetoimpedance (GMI) present high-sensitivity. Considering that, PWV is a significant risk factor for future cardiovascular disease and in view of some of the advantages of GMI sensors in relation to another sensing technologies, this doctoral thesis aims to develop a portable measurement system, non-invasive, low-cost, accessible and simple to use, capable of measuring PWV. For this purpose, we have developed a high-sensitivity transducers based on the impedance phase characteristics of GMI sensors, for measuring the arterial pulse wave velocity. In order to improve the performance characteristics of the transducers, computational and theoretical analysis in open and closed loop configuration were performed. The characterizations and experimental tests performed with the open-loop pressure transducer resulted in a sensitivity of 59.6 mV/kPa, and resolution of 192.8 Pa for an average of 30 samples, in the 1000 Hz passband. On the other hand, the closed-loop configuration presented a sensitivity of 54.2 mV/kPa, and a resolution of 206.0 Pa for an average of 30 samples, in the 32 Hz passband. In view of the considerable sensitivity and resolution obtained, it is proposed to employ a pressure transduction system that incorporates an incompressible chamber for mechanical amplification, in the measurement of arterial pulse waves. In this prototype, a small semi-rigid membrane located on the surface of the incompressible chamber is positioned over the surface of the skin, close to the artery of interest. In this way, small pressure changes on the skin surface, caused by the arterial pulse wave, cause a variation of the magnetic field on the sensing element. On the other hand, due to the high sensitivity presented by the magnetic transducer (GMI magnetometer) in the open-loop (0.2 mV/nT) and closed-loop (0.19 mV/nT) configurations, they were used to measure the shape pulse waveform without using an incompressible chamber for mechanical transduction. In this test, considering the adequate spatial resolution for the anatomical demands, a small magnetic marker is used, the magnetic marker is attached to the skin region over the artery of interest, and the GMI magnetic sensor is approached near the marker placed of the skin surface. Finally, the proposed configurations were analyzed and compared in order to identify the one with the best performance, which was used to measure PWV. As the study involves recording the pulse wave in research participants, the project was submitted for consideration and approved by the Research Ethics Committee of the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) 045/2020 – Protocol 83/2020. It is expected that the device developed will contribute to the technological advancement of the tools used in the health sector.
