Abstract

For a long time, people have carried out various studies on molecular communication (MC) and the Internet of Bio-Nanothings (IoBNT) in order to realize biomedical applications inside the 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 light absorption rates. Based on this, we propose a new through-body communication method. The nanomachine in the blood vessel transmits signals by releasing certain substances that can influence blood oxygen saturation. The change in blood oxygen saturation can be detected by an outside body device measuring the attenuation of the light through the blood. The framework of the entire communication system is proposed and mathematically modeled. Its error performance is discussed and evaluated. The mutual information (MI) of the designed communication system is also derived and calculated. This research will contribute to the realization of the connection of the IoBNT inside the human body to the outside device.

基于人体氧饱和度检测的全身信号传输系统的设计与分析

长期以来，人们对分子通信（MC）和生物纳米互联网（IoBNT）进行了各种研究，以实现人体内的生物医学应用。然而，如何实现这些应用与体外的通信成为一个新问题。一般来说，血液中的不同成分具有不同的光吸收率。基于此，我们提出了一种新的体内通信方法。血管中的纳米机械通过释放某些能影响血氧饱和度的物质来传递信号。血氧饱和度的变化可以通过体外装置测量光在血液中的衰减来检测。我们提出了整个通信系统的框架，并对其进行了数学建模。对其误差性能进行了讨论和评估。还推导和计算了所设计通信系统的互信息（MI）。这项研究将有助于实现人体内 IoBNT 与外部设备的连接。

期刊介绍： As a result of recent advances in MEMS/NEMS and systems biology, as well as the emergence of synthetic bacteria and lab/process-on-a-chip techniques, it is now possible to design chemical “circuits”, custom organisms, micro/nanoscale swarms of devices, and a host of other new systems. This success opens up a new frontier for interdisciplinary communications techniques using chemistry, biology, and other principles that have not been considered in the communications literature. The IEEE Transactions on Molecular, Biological, and Multi-Scale Communications (T-MBMSC) is devoted to the principles, design, and analysis of communication systems that use physics beyond classical electromagnetism. This includes molecular, quantum, and other physical, chemical and biological techniques; as well as new communication techniques at small scales or across multiple scales (e.g., nano to micro to macro; note that strictly nanoscale systems, 1-100 nm, are outside the scope of this journal). Original research articles on one or more of the following topics are within scope: mathematical modeling, information/communication and network theoretic analysis, standardization and industrial applications, and analytical or experimental studies on communication processes or networks in biology. Contributions on related topics may also be considered for publication. Contributions from researchers outside the IEEE’s typical audience are encouraged.
