METHOD FOR RESTORING THE SENSITIVITY, SPEED OR STABILITY OF A GAS-SENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To improve a chemo/electro-active material by increasing the sensitivity of the material; by increasing the stability of an electrical response characteristic of the chemo/electro-active material; or by increasing the speed with which a change in an electrical response characteristic of the chemo/electro-active material is detected.

SOLUTION: A method comprising: raising the temperature of the chemo/electro-active material to a second temperature at which the sensitivity of the chemo/electro-active material is increased to a second sensitivity that is greater than a first sensitivity; wherein the sensitivity of the chemo/electro-active material is the ratio given by ΔR/ΔC, where ΔR is the change in resistance, or in the size of a signal proportional to resistance, experienced by the chemo/electro-active material at a selected temperature as a result of a change in concentration of a component gas or subgroup of gases in a multi-component gas mixture, and ΔC is the change in concentration of the component gas or subgroup of gases.
