Several ways to gate a conducting polymer on a chip.
Backgating, electrochemical gating.
How does electrochemical gating work?
specifically regarding homogenous charge distribution or uniform electric field applied.

By "gating", do you maybe mean "coating" or "plating"? Where have you seen the term "gating"?

Gating as in for a transistor.
A three point probe with a source, drain, and a gate to apply a potential accross the channel.

In this case, I was saying, using a conducting polymer (or polymer film) as the channel between source and drain.
Backgating would be applying the electric field from under the substrate (i.e. the back)
electrochemical gating involves changing the gate potential on the channel by altering its local electronic environment in solution.
