Interfacial Shift Keying Allows a High Information Rate in Molecular Communication: Methods and Data

This study reports a method for molecular communication in fluids and provides a detailed description of the testbed and numerous experimental data. The prototype involves information being carried by fluorescent carbon nanoparticles. The details of the synthesis and fluorescence properties are also described. Signal modulation was achieved by exploiting the instability effect of an interfacial phenomenon known as viscosity fingering, which occurs when two miscible liquids with different viscosities or strong density variations contact one another. This modulation is called interfacial shift keying. The data confirm the reproducibility of the method. A new approach based on the deliberate superposition of two consecutive close releases is described in detail, and data from several experimental replicas are provided.
