Key result
A prototype hybrid microsystem using photoplethysmography and multiple optical wavelengths up to 1045 nm was developed for non-invasive continuous monitoring of heart rate, saturation, and blood glucose.
The study describes the development of a prototype hybrid microsystem for continuous non-invasive monitoring of vital signs and blood parameters using photoplethysmography.
The paper analyzes the existing non-invasive methods and tools for measuring and monitoring heart rate (HR), glucose saturation and human blood glucose level (BGL), shows ways of improving them to increase accuracy and expand the number of parameters obtained by these methods, which became the basis for creating a hybrid microsystem device for biomedical applications. A block diagram of the microsystem and a prototype of software and hardware tools for continuous monitoring of heart rate, BGL, saturation level and other blood parameters by photoplethysmography (PPG) have been developed. The proposed algorithms and tools provide primary processing of signals from optical sensors, calculation of pulse wave parameters, data transmission to mobile devices and a remote server, the possibility of calibration during operation based on research results.
