Contactless Human Vital Sign Monitoring System Using Millimeter Wave FMCW Radar for Healthcare Applications

During the COVID-19 pandemic, the need for contactless monitoring of people became very clear. To prevent the spread of the virus, physical interactions were minimized. As a result, many industries, including healthcare, are now focusing on touchless solutions. This research is driven by the need to tackle significant healthcare issues caused by contagious diseases, limited resources, and a shortage of healthcare workers. The paper discusses designing a contactless vital sign monitoring device that uses a 60 GHz FMCW radar and a thermal sensor to track respiratory rate, heart rate, and skin temperature. Heart sufferers and the elderly will benefit most from this device. It is appropriate for usage during sleep and in situations of viral illnesses due to its contactless…
