A wireless microwave sensor for remote monitoring of heart and respiration activity

The aim of this paper is to present a new microwave contactless sensor for heartbeat and respiration activities. The system is operating on 9 GHz. It's composed of two parts: a hardware one based on Doppler radar with a Digital Multimeter, and a software one based on the acquisition of the signals and the separation of the 2 informations of heartbeat and respiratory signals using simple filtering method with Labview.
