Ultra wideband radar for water detection in the human body

In this paper an Impulse Radio UltraWideband (IRUWB) radar for detecting water accumulation in the human body is proposed. The method of On-body water detection is investigated both in a simulator with a bladder model and measurement system with a phantom. The Vivaldi antenna is used in the measurement system. The simulation and measurement results show the feasibility of water detection in the bladder through the reflection from the boundary of muscle and urine. The proposed concept offers also potential for continuous, wireless detecting and monitoring of the human organs ( heart, lung and bladder) and vital functions.
