Abstract: A check valve for a fluidic system includes a fluidic conduit having an inlet with a first particle barrier, an outlet with a second particle barrier and a fluid chamber between the inlet and the outlet; and at least one particle disposed in the fluid chamber, the particle or particles aggregating at the first particle barrier to form a first hydrodynamic resistance when a first fluid pressure at the inlet is less than a second fluid pressure at the outlet, the particle or particles aggregating at the second particle barrier to form a second hydrodynamic resistance when the first fluid pressure is greater than the second fluid pressure.
