description: The aim of the work is to develop a device capable of studying the func-tional state of a person by continuous detection of pulse wave and its analysis by methods of heart rhythm variability (HRV). The following tasks are solved in the work: the choice of method for determining HRV parameters, analysis of circuit design, determining HRV parameters, typical for stress condition, de-termining HRV parameters, typical for alcohol intoxication state. Comparison of various HRV indices and justification of their choice, block diagram of the device, description of the light filter operation are given in the work. In the course of the work it was determined that the device would have to be individually calibrated. The confidence intervals on the multiple samples were found to be Â±3.35 in the normal state and Â±2.6 in the stress state. Once calibrated, this device allows for unambiguous detection of body abnor-malities associated with stress, heavy physical exertion, and alcohol intoxica-tion.
