Development of a wireless antenna and monitoring system for microwave based vital sign and lung water measurement

A wireless microwave based antenna monitoring system has been developed for vital signs and lung water measurements. The system employs a unique electromagnetic energy coupling sensor/antenna and is also equipped with a mobile app to display the processed values in real time and facilitate use by mobile users. New RF components have been used and this eliminated the need for a costly and bulky network analyzers. The developed system is more suitable for clinical use and for remote monitoring of remote patients. Accuracy of the developed wireless system has been validated by comparing results with traditional network analyzer measurements and excellent agreement was observed.
