Information Science
This book provides an easy-to-understand explanation of radio wave measurement and signal processing methods for wireless human body sensing, which enables continuous measurement of multiple vital signs without contact. It explains in detail the principle and application methods of wireless human body sensing, which uses microwave and millimeter waves to measure human vital signs without contact using radio wave sensors such as radar (wireless human body sensing). Wireless human body sensing can dramatically improve accuracy and efficiency in monitoring at medical facilities such as hospitals, daycare facilities such as nursery schools, and nursing care facilities, and it can be combined with AI and cloud technology to make it easy for anyone to grasp their own vital signs on a daily basis. On the other hand, body movements based on vital signs vary only slightly compared to movements of hands and feet, and it is not easy to accurately measure vital signs of subjects using radio wave sensors such as radar. This book provides an easy-to-understand explanation of radio wave measurement and signal processing methods that are practically applicable, from antenna engineering and basic medical knowledge that form the foundation of wireless human body sensing, to radio wave measurement and signal processing methods that are practically applicable.
