Contactless medical sensing

Radar technologies are emerging for health monitoring. The possibility of characterizing speed and distance in a contactless way opens up a range of practical applications, such as allowing elderly to reside longer in their familiar environment. Research has been focusing at first at single radar solutions targeting vital signs monitoring and detection of falls. Over time, these speed based parameters got combined with in-door localisation as well. To increase flexibility further, recent developments evolve towards wireless radar sensor networks. In this overview paper, the state-of-art is illustrated by means of various practical examples.
