ABSTRACT:
A chemical switch device and method of sensing the presence of a chemical constituent in an ambient environment, the chemical switch device comprising a film which irreversibly reacts upon exposure to specific chemical components in the environment under the conditions of measurement. The reactions can lead to large changes in the physical and chemical properties of the film which are measurable electrically, optically or by other methods.
