This article presents a methodology for the preparation of a phantom arm model to be used for evaluating the performance of intra-body communications specifically and body area networks (BANs) in general.

The basic procedures are described for preparing tissue that mimics materials for each of the five basic tissue layers: skin, fat, muscle, cortical bone, and bone marrow. Matching materials for mimicking the dielectric properties of each tissue, with a mimic accuracy of at least 90 percent, were selected, after conducting experimental testing on more than 50 different test samples that were prepared using different techniques and mixture concentrations. The final arm phantom was then fabricated and tested. The experimental results, mainly the gain/attenuation profile, were then displayed and compared with those obtained from the real subjects with similar experimental setup conditions showing close to perfect match, proving the high accuracy of the fabricated arm phantom model in mimicking the dielectric behavior of real body parts, over the frequency range of interests for intra-body communications (100 kHz to 100 MHz). To date, this is the first accurate physical five-layer phantom arm model fabricated for intra-body communication applications covering this frequency range and with such high accuracy.
