Ubiquitous Microwave and mm-Wave Radars: from Worker Health Monitoring to Assistive Devices for Impaired People

Modern radars demonstrated to have a disruptive impact in different sectors within the medical and biomedical fields. The capability to detect information like the range and speed of the targets was expanded by exploiting the measurement of sub-millimeter displacements and the ability to extract the characteristic micro-Doppler signature of a target. In this contribution, some recent advances concerning the radar sensing technology aimed at assisting the mobility or the communication of impaired people or at monitoring the health status of workers will be presented. The related experimental activity will highlight the advantages, potential and future challenges of radio-frequency and mm-wave radar sensing.
