Contactless Radar Sensing for Health Monitoring

Contactless radar and radio frequency (RF) sensing has recently gained much interest in the domain of health care and assisted living, due to its capability to monitor relevant parameters for the health and well‐being of people. Applications range from the monitoring of respiration and heartbeat to mobility levels, gait and locomotion parameters, and behavioral patterns. What makes radar sensing attractive compared to alternative and complementary technologies such as video‐cameras, wearables, or ambient sensors, is their contactless capabilities, whereby no sensors need to be worn by the people monitored, and no plain images or videos need to be collected in private spaces and homes.
