Microfluidic AND gate design for molecular communication

The design of components with molecular communication (MC) functionalities can bring new opportunities to facilitate emerging applications in fields from personal healthcare to modern industry. In this paper, we propose the microfluidic AND gate design, and we also establish a general mathematical framework to theoretically characterize this microfluidic circuit. Based on these, we first derive the output concentration distribution of our proposed AND gate design, and then provide the insight into the design parameter selection to ensure an exhibition of desired behaviour. Simulation results obtained in COMSOL not only show the desired behaviour of the proposed AND gate, but also demonstrate the accuracy of our proposed mathematical framework.
