An electrokinetic fluidic system for controlling liquid flow, comprising:
- a) a first and a second electrode arranged in a respective vessel, said electrodes comprising a conductive, electrochemically active electrode material selected from a pi-conjugated polymer-based material and a metal oxide material, said electrode material being adapted to be subjected to an electrochemical reaction when in use in said electrokinetic fluidic system, and
- b) a channel arranged as a passageway between the two vessels, said channel allowing flow of electrolyte between said two vessels,
- wherein the fluidic system is designed such that during said electrochemical reaction the pH of the electrolyte is constant or almost constant and there is a gas bubble free environment at said first and second electrode, and
- wherein said channel is a porous material of solid or semi-solid material allowing flow of electrolyte.
