Microfluidic Systems for Molecular Communications: A Review From Theory to Practice

The paper presents the significance of microfluidic technology in advancing Molecular Communications (MC). It highlights the transition from theoretical MC models to practical applications, emphasizing the role of microfluidics in validating and advancing MC concepts. The paper covers various aspects including theoretical principles, simulation tools, practical realizations, and envisioned applications. We also present various microfluidic testbeds, detailing their design, capabilities, and applications in advancing MC. To bridge the gap between theoretical models and practical outcomes in MC, this work demonstrates the potential of microfluidics in the practical realization of MC systems.
