The goal of disease pre-screening is to detect potential health disorders or diseases in people who do not have any symptoms of disease. Non-invasive biomedical sensor devices offer a variety of benefits such as early detection and thus prevention of the risk of infection, ease of use and suitability for long-term monitoring. This book is focused on using non-invasive biomedical sensor devices, IOT solutions, and knowledge database solutions for pre-screening of diseases so that the risk of disease is reduced, or it can be detected early enough to treat the disease most effectively.
