Abstract
Molecular communication (MC), as a current research hotspot, provides a new method to achieve the communication between nanodevices inside the human body. However, there are still challenges in transmitting information from nanodevices inside the human body to the outside body. In this paper, a MC scheme based on light absorption is proposed for through-body communication where the information is transmitted by converting molecular signals into optical signals. A testbed is implemented, where animal blood and meat is used to mimic living environment more practically. Indocyanine green is used as information particle which is biocompatible. We carry out sequence transmission experiments with 660nm and 800nm light sources, and investigate the effect of the number of meat layers between the sensor and the light source on the transmission performance. The experimental results show that the proposed MC system can transmit information from the inside pipe through the meat, and as the thickness of the meat above the pipe increases, the light source with stronger tissue penetration ability can ensure a more reliable transmission.
分子通讯（MC）作为当前的研究热点，为实现人体内纳米器件之间的通讯提供了一种新方法。然而，从人体内部的纳米器件向体外传输信息仍面临挑战。本文提出了一种基于光吸收的穿越人体通信 MC 方案，通过将分子信号转换为光信号来传输信息。本文使用动物血液和肉类作为试验平台，以更实际地模拟生活环境。吲哚菁绿被用作信息粒子，它具有生物相容性。我们用 660nm 和 800nm 光源进行了序列传输实验，并研究了传感器和光源之间的肉层数量对传输性能的影响。实验结果表明，所提出的 MC 系统可以从管道内部通过肉层传输信息，而且随着管道上方肉层厚度的增加，组织穿透能力更强的光源可以确保更可靠的传输。
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.
