description: This work is devoted to the creation of a demo layout with two multiplexed fiber-optic pressure sensors with intensity polling using a digital camera. The main purpose of the study was to develop a system for measuring the speed of a human pulse wave. To achieve this goal, a fiber-optic micro-displacement sensor with increased sensitivity was developed, various types of membranes for the pressure sensor were manufactured, experiments were conducted to test them and determine their characteristics. The development of the code for processing the signal from the sensors was carried out in the MATLAB environment. Models for 3D printing of system elements were drawn in the AutoCAD program. Pulse wave measurement experiments were carried out on the radial and carotid arteries using the created sensors. As a result of the work, a pulse wave velocity measurement system was implemented, including fiber-optic connectors, sensitive membranes and sensor housings. Different types of membranes were tested, which allowed us to determine the most suitable â flat rubber membranes. The experiments carried out confirmed the possibility of measuring the pulse wave velocity, and also showed a change in velocity after taking sugar to the subjects. Thus, all the tasks were successfully completed. The results of the study can be used in medicine in the development of inexpensive devices for monitoring and diagnosing the state of the cardiovascular system, as well as for scientific research in the field of biomechanics and medical physics. The created system has the potential for further improvement by improving signal processing algorithms and improving measurement accuracy.
