Abstract
Based on the available results, a compact device, an attachment to a smartphone, has been developed that provides registration of a univariate photoplethysmogram signal (vascular blood filling recorded by an optical sensor) and an assessment of the spectral characteristics of blood pressure variability and pulse rate variability, as well as an assessment of the degree of synchronization between the circuits of autonomous regulation of blood circulation.
A prototype of the device has been developed using of a promising element base and a wireless communication channel with a smartphone, will allow in the future to autonomously solve a number of problems of medical diagnostics.
