| 摘要 |
The present invention relates to sensors and more particularly to gas sensors suitable for use in gases and gaseous mixtures. The present invention provides a gas sensor comprising a liquid electrolyte (4) and two or more electrodes (2), (3) in communication with the said liquid electrolyte and capable of being contacted with a gas or gaseous mixture, the arrangement being such that two or more of the electrodes produce different potentials when in contact with the said gas or gaseous mixture. A liquid electrolyte may be, for example, a thin film of water, or a thin film of an aqueous solution, in communication with the electrodes. |
