Abstract
For a long time, people have carried out various studies on molecular communication and nano information network in order to realize biomedical applications inside human body. However, how to realize the communication between these applications and the outside body has become a new problem. In general, different components in the blood have different absorption rates of the different light. Based on this, we propose a new through-body communication method. The nanomachine in the blood vessel transmits signal by releasing certain substances which can influence blood oxygen saturation. The change of blood oxygen saturation can be detected by a outside body device measuring the attenuation of different light through blood. The framework of the entire communication system is proposed and mathematically modeled. Its error performance is discussed and evaluated. This research will contribute to the realization of the connection of communication systems inside and outside the human body.
