Design of wearable intra-body communication devices

体内通信是一种利用人体作为传输媒介的新型数据传输方式。简化了用于电磁分析的详细的人体数值模型，只使用了皮肤、脂肪和肌肉这三层人体组织，而不牺牲分析的准确性。这种三层模型的形状修改容易得多，而且这种结构也适用于制作实验用的体模。它的电学特性比由均匀材料制成的普通体模更接近人体。

Intra-body communication is a new data transmission method that uses human body as part of the transmission medium. Detailed numerical human body model for electromagnetic analysis has been simplified by using only three layers of body tissues, namely, skin, fat, and muscle, without sacrificing the accuracy of analysis. Shape modification is much easier with this three-layered model, and this structure is also suitable for fabricating phantom for experiments. Its electrical characteristic is closer to human body than that of the ordinary phantom made of homogeneous material.
