1. A gas sensor for reducing or oxidizing gases, comprising:
- a) a number of gas sensitive, longitudinal segments consisting of a semiconductive metal oxide film,b) each of said segments having two strip electrodes in contact therewith,c) said segments having different properties with respect to reducing or oxidizing gases such that different conductivity changes are generated from said segments upon exposure to oxidizing or reducing gases,d) said segments defining together a continuous surface area, ande) said strip electrodes including outer electrodes extending at opposite ends of said continuous surface area so as to limit said continuous surface area, and inner electrodes extending between, and parallel to, said outer electrodes so as to divide said continuous surface area into said longitudinal segments.

Abstract
In a gas sensor for sensing reducing or oxidizing gases which comprises a semiconductive metal oxide film, there are provided stripe-like outer electrodes which define therebetween a continuous surface area and stripe-like inner electrodes which extend between, and parallel to, the outer electrodes so as to divide the continuous surface area into longitudinal segments which have different properties with respect to reducing or oxidizing gases such that different conductivity changes are generated for the different segments upon exposure to oxidizing or reducing gases.
