Design files presented have not gone through peer-review at this time. Designs have been tested in the lab and are a part of a publication currently in preparation. After publication, a link to the manuscript will be provided here. Electrochemical cell specifically designed to hold ITO-PET electrodes in a fixed 4mm bending radius position with the electrolyte at a specified height. Compartments on the side are for the reference electrode (we used Ag/AgCl) and the counter electrode (we used either a carbon plate or platinum plate). Electrolyte was added until it flowed into the overflow channel, then electrolyte was removed until the overflow channel was empty again. This ensures a consistent electrolyte height (constant electrode surface area).
