Abstract

We investigate a wireless communication system for an in vivo healthcare chip. In this paper, we present measured attenuation characteristics through the human body at several frequencies. In the measurement, we use physiological saline and fresh meat instead of a real human body. From the measured results, we found that 13.56 MHz has an attenuation of 47 dB and is suitable for the proposed system.
