Abstract

Droplet microfluidics is a research area rapidly evolving due to its vast range of potential applications in several fields ranging from medicine to biodefense, and drug administration. In this context, it is crucial to identify efficient and effective methods for communicating by means of droplets. Various techniques have been proposed in the past to encode data by exploiting droplets, such as utilizing droplet size, droplet composition, or the presence/absence of droplets. Nevertheless, these methods are plagued by propagation delays within the channel, resulting in the impossibility to rapidly deliver information at the receiver. To address this issue, this paper introduces a novel methodology for encoding information. The proposed approach involves the instantaneous manipulation of a train of dye drops within a continuous oil phase to induce variations in flow properties. By capitalizing on the stable and laminar flow of the drops, our objective is to encode data instantaneously by altering the dye-oil pressure pairs. To better predict and explain the microfluidic dynamics in the channel, we develop a model of the proposed scheme.

微流控通信中的液滴移速键控建模

液滴微流控技术是一个快速发展的研究领域，因为它在医学、生物防御和药物管理等多个领域都有广泛的潜在应用。在此背景下，确定高效的液滴通信方法至关重要。过去曾提出过多种利用液滴进行数据编码的技术，如利用液滴大小、液滴成分或液滴的存在/不存在。然而，这些方法都受到信道内传播延迟的困扰，导致无法在接收器处快速传递信息。为解决这一问题，本文介绍了一种新的信息编码方法。所提出的方法涉及在连续油相中瞬时操纵一列染料滴，以引起流动特性的变化。利用液滴的稳定层流特性，我们的目标是通过改变染料-油压对瞬间编码数据。为了更好地预测和解释通道中的微流体动力学，我们建立了一个拟议方案的模型。

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.
