Design of organ phantom for body-centric wireless system

Three organ phantoms (Heart, Liver, Stomach) were designed for experimentally evaluating the performance of implantable and wearable devices. It is necessary to use organ phantoms in body-centric wireless system because the performance of devices is strongly affected by surrounding materials. In order to develop the organ phantom, materials to make phantom were surveyed and the composition was optimized. The optimized organ phantoms were fabricated and electrical properties were measured. The measured relative permittivity and conductivity values are within the error tolerance over the wide frequency range.
