Microfluidic pulse shaping methods for Molecular Communications

Molecular Communication (MC) is a bio-inspired communication modality that utilizes chemical signals in the form of molecules to exchange information between spatially separated entities. Pulse shaping an important process all systems, as it modifies waveform transmitted match characteristics channel for reliable and high-speed transfer. In MC unconventional architectures components, such transmitters receivers, complex, nonlinear, time-varying nature channels make pulse even more important. While several methods have been theoretically proposed MC, their practicality performance are still uncertain. Moreover, majority recently experimental testbeds rely on microfluidics technology lack incorporation programmable methods, which hinders accurate evaluation techniques practical settings. To address challenges associated with microfluidic we provide comprehensive overview generation experimentally validated whose can inform design systems testbeds. These include those based hydrodynamic acoustofluidic force fields, well electrochemical reactions. We also discuss fundamental working mechanisms system these techniques, compare performances terms spatiotemporal resolution, selectivity, complexity, other metrics relevant applications, feasibility applications.
