Investigations of the gas sensitivity of specific metal-oxide thin films (such as SrTiO3 and CeO2) have shown that at particular combinations of gas composition and sensor material there exists a specific temperature at which the gas mixture changes from being an 'oxidising' agent to a 'reducing' agent. It is shown that this effect can be used to manufacture a temperature sensor that is calibrated in the desired temperature range (500°C to 1000°C) and whose resistance exhibits an exponential dependence on temperature. The resolution of this principle of measuring high temperatures is better than ± 1K.
