Chemical Reactions-Based Microfluidic Transmitter and Receiver for Molecular Communication
摘要：
能够通过分子和化学过程处理和交换信息的通信系统的设计是一个快速发展的跨学科领域，它有望彻底改变我们实现计算和通信设备的方式。虽然近年来分子通讯（MC）理论有了很大的发展，但在设计具有MC功能的组件方面，更实际的方面仍然很少探索。基于此，我们设计了一个基于化学反应的微流控微流控系统，该系统包括微流控微流控发射器和微流控微流控接收器。考虑到现有的MC文献的信息传输通过分子脉冲调制，所提出的微流体MC发射器是能够产生连续预定义的脉冲形状的分子浓度的矩形触发信号，使用化学反应的启发，细胞如何产生脉冲形状的分子信号在生物学。我们进一步设计了一种微流控MC接收器，能够使用阈值反应和放大反应将接收信号解调为矩形输出信号。我们的基于化学反应的微流控分子通信系统是可重复的和精心设计的，更重要的是，它克服了细胞中生物过程的速度慢，不可靠和不可扩展性。为了揭示设计见解，我们还推导出我们设计的微流体发射器和接收器的理论信号响应，这进一步促进了发射器的设计优化。我们的理论结果通过COMSOL Multiphysics有限元求解器进行模拟验证。我们证明了预定义的性质所产生的脉冲和解调的矩形信号连同它们对设计参数的依赖。
英文摘要：
The design of communication systems capable of processing and exchanging information through molecules and chemical processes is a rapidly growing interdisciplinary field, which holds the promise to revolutionize how we realize computing and communication devices. While molecular communication (MC) theory has had major developments in recent years, more practical aspects in designing components capable of MC functionalities remain less explored. Motivated by this, we design a microfluidic MC system with a microfluidic MC transmitter and a microfluidic MC receiver based on chemical reactions. Considering existing MC literature on information transmission via molecular pulse modulation, the proposed microfluidic MC transmitter is capable of generating continuously predefined pulse-shaped molecular concentrations upon rectangular triggering signals using chemical reactions inspired by how cells generate pulse-shaped molecular signals in biology. We further design a microfluidic MC receiver capable of demodulating a received signal to a rectangular output signal using a thresholding reaction and an amplifying reaction. Our chemical reactions-based microfluidic molecular communication system is reproducible and well-designed, and more importantly, it overcomes the slow-speed, unreliability, and non-scalability of biological processes in cells. To reveal design insights, we also derive the theoretical signal responses for our designed microfluidic transmitter and receiver, which further facilitate the transmitter design optimization. Our theoretical results are validated via simulations performed through the COMSOL Multiphysics finite element solver. We demonstrate the predefined nature of the generated pulse and the demodulated rectangular signal together with their dependence on design parameters.
