Investigation of a Time Domain Microwave System for Biomedical Applications

A time domain microwave system completely based on off-the-shelf components is developed for biomedical applications. This work is the investigation of this system for two different type of applications: medical diagnosis and vital sign detection. The results show that the system is accurate enough for most of the measurement scenarios. Both the respiration rate and heartbeat rate are detectable with the system and the success rate of respiration detection is 100% for seventeen tests we have performed.
