{ntb_intro_text}An ambient temperature oxygen microsensor, based on a Nafion polymer electrolyte, has been developed. A challenge in the operation of Nafion-based sensor systems is that the conductivity of Nafion film depends on the humidity in the film. Nafion film loses conductivity when the moisture content in the film is too low, which can affect sensor operation.{/ntb_intro_text}
