Fabrication and optimization of silver electrode porous membrane microfluidic devices for electrokinetic energy harvesting applications
Electrokinetic phenomena associated with fluid flow in micro-channels have been studied for different applications. For example, electro-osmotic flow pumps involve driving a fluid along a narrow channel by applying an electric field along the length of the channel. This process is reversible, thus it is possible to use for electric energy generation where driving an electrolyte fluid along a narrow channel by a pressure difference at both sides of the channel results in an electric potential along the length of the channel. Such electric potential can then be harnessed to drive an electric current through an external load. Theoretical conversion efficiencies of up to 12% have been estimated, and experiments have claimed 3% efficiency using flat 75 nm microfabricated channels on silicon.

Abstract
Electrokinetic phenomena associated with fluid flow in micro-channels have been studied for different applications. For example, electro-osmotic flow pumps involve driving a fluid along a narrow channel by applying an electric field along the length of the channel. This process is reversible, thus it is possible to use for electric energy generation where driving an electrolyte fluid along a narrow channel by a pressure difference at both sides of the channel results in an electric potential along the length of the channel. Such electric potential can then be harnessed to drive an electric current through an external load. Theoretical conversion efficiencies of up to 12% have been estimated, and experiments have claimed 3% efficiency using flat 75 nm microfabricated channels on silicon.
