A transmission line simulator for applications to TDR measurements and TDR-based sensors is presented. The proposed simulator, fully developed in MATLAB environment, is designed to be a fast, efficient and easily customizable tool, and its performance are compared with commercial simulation software packages. The simulator is intended for measuring arbitrary profiles of primary parameters (R, C, G, L) of a transmission line, by matching simulated TDR waveform with experimental TDR data. In the paper, this use is demonstrated by measuring the parameter profiles of actual coaxial cables.

One of the major goals of Health 4.0 is to offer personalized care to patients, also through real-time, remote monitoring of their biomedical parameters. In this regard, wearable monitoring systems are crucial to deliver continuous appropriate care. For some biomedical parameters, there are a number of well established systems that offer adequate solutions for real-time, continuous patient monitoring. On the other hand, monitoring skin hydration still remains a challenging task.
