Abstract:
We justify the use of mobile sensors operating on various physical phenomena to expand the functionality of rapid assessment of a person's health status. Advantages of using optical sensors for measurements using blood flows are outlined. Difficulties in taking measurements and processing optical signals when using mobile sensors to obtain reliable real-time information are established. New designs of mobile sensors for recording pulse waves and reflected optical signals from tissues with blood microcirculation are proposed, which are combined into a hardware and software complex. New methods for processing recorded optical images, reflected signals and absorption in vessels and tissues are proposed. New research results are presented that make it possible to establish previously undetected deviations in the functioning of the human cardiovascular system. A new, more accessible method for determining the value of maximum oxygen consumption by the human body using the developed hardware and software complex in real time is proposed. The obtained data are compared with the results of measurements on certified medical equipment. This method allows one to expand the possibilities of using the hardware and software complex in health assessment of professional and amateur athletes, as well as members of special forces units.
