模拟人体电学特性的模型被广泛用于医疗设备等的安全评估。虽然高水凝胶模体在高频波段是有用的，但在低频波段还没有能模仿活体人体的模体。一个生物体的相对介电常数不能通过在10兆赫或更少的频带内调整物质的数量来获得。因此，本研究在传统模体中加入碳微线圈（CMC），提高了低频段的相对介电常数。
Phantoms that mimic the electrical properties of the human body are widely used for the safety assessment of medical equipment, etc. Although a high hydrous gel phantom is useful in the high-frequency band, there is no phantom that can mimic the living human body in the low-frequency band. A living body’s relative permittivity cannot be acquired by adjustment of the quantity of material in a frequency band of 10 MHz or less. Therefore, a carbon microcoil (CMC) was added to the conventional phantom in this study, and the relative permittivity in the low-frequency band improved.
