基于化学反应的微流控电路分子通讯的数字信号处理

Digital Signal Processing for Molecular Communication via Chemical Reactions-based Microfluidic Circuits

Dadi Bi, Yansha Deng

摘要:

基于化学反应的微流控回路有望为在分子域上执行信号处理功能提供新的机会。为了实现这一愿景,在这篇文章中,我们开发并提出了基于化学反应的微流控电路的数字信号处理能力。为了便于微流控回路设计,我们描述了一种使用五层架构的微流控回路:1)分子传播; 2)化学转化; 3)微流控模块; 4)微流控逻辑门;和5)微流控回路。我们首先确定第1级和第2级的组件,并介绍它们的组合如何构建第3级的基本模块。然后,我们组装基本模块,构建五种类型的逻辑门4级,包括与,与非,或,或非,和“异”门,这显示了微流控电路的可重用性和模块化的优势。最后但并非最不重要的是,我们讨论了基于Level 4的数字逻辑门设计,构建和测试具有复杂信号处理功能的Level 5微流体电路的挑战和潜在解决方案。

英文摘要:

Chemical reactions-based microfluidic circuits are expected to provide new opportunities to perform signal processing functions over molecular domain. To realize this vision, in this article, we exploit and present the digital signal processing capabilities of chemical reactions-based microfluidic circuits. Aiming to facilitate microfluidic circuit design, we describe a microfluidic circuit using a five-level architecture: 1) Molecular Propagation; 2) Chemical Transformation; 3) Microfluidic Modules; 4) Microfluidic Logic Gates; and 5) Microfluidic Circuits. We first identify the components at Levels 1 and 2, and present how their combinations can build the basic modules for Level 3. We then assemble basic modules to construct five types of logic gate for Level 4, including AND, NAND, OR, NOR, and XOR gates, which show advantages of microfluidic circuits in reusability and modularity. Last but not least, we discuss challenges and potential solutions for designing, building, and testing microfluidic circuits with complex signal processing functions in Level 5 based on the digital logic gates at Level 4.
