electric double layer

electric double layer

[i′lek·trik ¦dəb·əl ′lā·ər]
(physical chemistry)
A phenomenon found at a solid-liquid interface; it is made up of ions of one charge type which are fixed to the surface of the solid and an equal number of mobile ions of the opposite charge which are distributed through the neighboring region of the liquid; in such a system the movement of liquid causes a displacement of the mobile counterions with respect to the fixed charges on the solid surface. Also known as double layer.

electric double layer capacitors (supercapacitors).
It is well-known that when solid objects are placed in contact with an aqueous electrolyte solution, they usually acquire a surface charge and spatial distributions of charge and electric potential, known as the electric double layer (EDL), appear close to the interfaces.
Electrokinetic phenomena in microfluidics are caused by the interaction between the applied electric field and the diffusion layer in the electric double layer. More electrokinetic phenomena studied at present include electrophoresis, dielectric electrophoresis, electroosmotic flow, and induced electroosmotic flow.
In clay bearing rocks, the presence of a connate brine results in the so-called surface effects: electric double layer polarization (i.e., Stern layer polarization) and Maxwell-Wagner space-charge polarization.
The paper details how electricity is generated using FFNG - an electric double layer is created around the fiber, and the flowing solution composed either of a saline solution or water, which then distorts the charge distribution in the blood vessel and generates electricity along a long axis.
