Ultra-wideband Signals for the Detection of Water Accumulations in the Human Body

In this paper, the concept for an Ultra-wideband (UWB) radar system for the detection and quantification of water accumulations in the human body is presented. With this system, the amount of water in human organs (e.g. the bladder or the lung) can be estimated by processing reflected UWB signals. A simulation-based prove of concept of this approach is presented and it is shown that the system promises a feasible way to implement a mobile on-body water detection system for medical applications. Based on the simulation results, it can be concluded that UWB technology is a very promising opportunity for the realization of a mobile and continuous on-body water detection system that can drastically reduce the costs in different areas in the fields of urology and cardiology.
