Design of Radar-Based Portable System for Monitoring of Human Vital Signs with Renewable Energy Resources

This paper presents the design of a portable radar-based system for non-invasive monitoring of human vital signs, including heart rate (HR) and respiratory rate (RR) signals. The system is user-friendly and applicable in various settings, such as hospitals, clinics, and homes. The design process involves several stages, including submodules, system requirements identification, design, prototype development, data collection and analysis, optimization, and validation. It measures physiological signals, such as heart rate, breathing rate, and body movement, using electromagnetic waves. To minimize battery replacements or charging, the system integrates renewable energy systems like solar power or kinetic energy capture. Accuracy evaluation of the system is performed by collecting and analyzing data on vital signs, including heart rate, respiratory rate, and body movement, from a group of volunteers. The proposed system provides a sustainable, portable, and non-contact solution for monitoring HR and RR signals, which can enhance the accuracy of diagnosis and treatment in various biomedical applications.
