Optimization of Nafion Polymer Electrolyte Membrane Design and Microfabrication

Nafion is a solid electrolyte polymer that can be used as a sensor membrane in microfabricated electrochemical oxygen sensors. It allows ions to be transported between the sensor electrodes and removes the need for a liquid electrolyte. Here we used a series of small square Nafion test structures, fabricated on a variety of materials using standard thin-film patterning techniques, to optimize the ...
