22. A method, comprising:
positioning a fluid flow control device coupled to tubing string within a borehole formed through a subterranean formation, the fluid flow control device including:
an inlet port, allowing a downhole fluid of the borehole to flow into the fluid flow control device;
an outlet port, allowing the downhole fluid to flow out of the fluid flow control device;
a fluid chamber positioned between the inlet port and the outlet port, wherein an electrokinetic film is located in an interior of the fluid chamber and is capable of generating a voltage as the downhole fluid flows over the electrokinetic film; and
an electronics system able to determine one or more voltage parameters at one or more measuring locations within the fluid chamber using the generated voltage;
analyzing the one or more voltage parameters using the electronics system; and
determining a one or more downhole fluid characterizations using the one or more voltage parameters.
