Abstract
A gas sensor for sensing a gas in a humid environment includes a first electrode layer, a second electrode layer that is spaced apart from the first electrode layer, and a gas sensing layer that electrically interconnects the first electrode layer and the second electrode layer. The gas sensing layer is made of a hygroscopic electrically insulating material.
Claims14
A gas sensor comprising:
- a first electrode layer;
- a second electrode layer spaced apart from said first electrode layer;
- and
- a gas sensing layer interconnecting said first electrode layer and said second electrode layer, the gas sensing layer made of a hygroscopic electrically insulating material and configured to transition between an insulative state before a gas to be detected contacts therewith and a conductive state when the gas to be detected contacts therewith in a humid environment, wherein the gas is dissociated to generate conductive substances upon contact with water.
