Abstract
A microfabricated electrochemical gas sensor is disclosed. The sensor includes electrodes produced from conductor layers, a capping layer, microcavities through the conductor layers and the capping layer, a cavity connecting the microcavities, and an electrolyte filling in the space created by the cavity and the microcavities in the substrate. The microcavities allow gases to pass through but retain the electrolyte through surface tension.
