Programmable Fluidic Spinner Array: Biomimetic Transport from Particles to Liquid Droplets

We propose a new paradigm in fluidic control through an array of programmable spinners that generate controlled vortices, enabling boundary-driven transport of particles and droplets, analogous to transport mechanisms in biological systems. This approach eliminates the need for pressure differentials typically employed in conventional fluidic devices, relying instead on local boundary conditions to govern fluid flow. By dynamically adjusting the direction and speed of the spinners, we can control the movement and velocity of particles, offering a tunable, programmable system. The channeless nature of this design allows for dynamic reconfiguration of transport pathways, providing flexibility in directing particles or droplets to different target locations. This system holds promise for applications in controlled chemical reactions, material assembly, and soft matter physics, offering new avenues for experimental investigation.
