Claim:
1. A polymer film electrode comprising: (i) an electrically-conductive substrate; and (ii) an electrically-conductive polymer applied to said electrically-conductive substrate, wherein said electrically-conductive polymer is in electrical contact with said electrically-conductive substrate, and said electrode exhibits ohmic behavior over a range of about 800 Hz to about 100 kHz; wherein the electrode further exhibits ohmic behavior over at least one range selected from the group consisting of: 50 Hz to 100 Hz, 25 Hz to 50 Hz, 10 Hz to 50 Hz, 5 Hz to 50 Hz, 10 Hz to 25 Hz, 5 Hz to 25 Hz, 1 Hz to 25 Hz, 5 Hz to 10 Hz, and 1 Hz to 10 Hz; wherein said electrically-conductive polymer is a compact layer that is not permeable to a solution adjacent to the electrode and is overlaid with a structure that is ionically permeable.
