“…Moreover melon pulp has higher dielectric constant than its skin (Nelson et al, 2008). The same differences can be identified as regards grey matter and muscle in comparison to human skin (Young et al, 2002). However, electric properties of materials are complex and vary depending on frequency of the applied field, temperature, and other parameters.…”

“…The accuracy of phantoms with respect to real tissues is often specified by the root-mean-square error (RMSE), but also by the mean squared error (MSE) and the relative error. From Table II, one can observe that many of them have large deviations [40], [96], [98], [101], [103], [104]. Others do not even conform to tissue values, but such phantoms are created so that the differences between their values are equivalent to those of the tissues of interest [92], [100].…”

“…Muscle phantoms, in particular, are given in four different works in Table II, with a high contrast between their errors. Both [40] and [98] exhibit a high deviation from the reference values, whereas [101] just provides a first-order match. The muscle phantom from [39], [41] has the highest accuracy, with a really low RMSE.…”

In-body sensor networks are those networks where at least one of the sensors is located inside the human body. Such wireless in-body sensors are mainly used for medical applications, collecting and monitoring important parameters for health and diseases treatment. The IEEE Standard 802.15.6-2012 for Wireless Body Area Networks (WBAN) considers in-body communications in the Medical Implant Communication Service (MICS) band. Nevertheless, high data rate communications are not feasible at the MICS band due to its narrow occupied bandwidth. In this framework, Ultra-Wideband (UWB) systems have emerged as a potential solution for in-body high data rate communications, due to its miniaturization capabilities or low power consumption. In the last years, some open issues have determined the research about in-body propagation. Firstly, the propagation medium, i.e., the human body tissues, is frequencydependent and exhibits a large attenuation at UWB frequencies. Secondly, the behavior of the in-body antennas is highly dominated by the surrounding tissues. Thus, the in-body channel characterization in UWB depends not only on the channel behavior itself, but also on the methodology of characterization. This paper intends to outline the research performed in the field of UWB in-body radio channel characterization considering the propagation medium, as well as the methodology of analysissoftware simulations, phantom measurements, in vivo measurements-. Thus, authors provide an overall perspective of the current state of the art, limitations for the analysis of in-body propagation, and future perspectives for UWB in-body channel analysis.

“…Regarding mechanical properties, there are liquid [5,6], solid [7][8][9][10] and gel based phantom materials [11][12][13][14][15][16]. When liquid mixtures are used, always appropriate containers are needed that hold the liquid.…”

Abstract-We present a new composite material containing calcium alginate microspheres incorporated into an epoxy matrix. The new material is mechanically stable and does not degrade over time. Its dielectric properties are extracted by model calculations and compared to the properties of some selected human tissues. Good agreement is observed, which identifies the proposed composite material as a good candidate for the use as a phantom material. The presented material is a two component composite and it is shown how its effective properties can be predicted by using appropriate mixing formulas.
