Abstract

Autonomous fluidic components that function at ultra-low Reynolds number (e.g., Re < 0.1) are critical to the advancement of integrated microfluidic circuitry. Here we present a single-layer microfluidic "disc" diode, which includes a free-moving cylindrical "disc" - constructed in situ using optofluidic lithography - that is transported to or away from the entrance of a docking channel to obstruct or promote fluid flow, respectively. COMSOL simulations yielded a theoretical Diodicity (Di) of 27.8. Experimental results revealed Di's ranging from 2.29±0.58 to 3.84±1.76 for a one-disc system, and 4.69±1.21 to 6.66±1.10 for a four-disc (in series) system, corresponding to Re < 0.025 flow.
