Thaditionally, solid-state gas sensors have a two-electrode configuration, where the gas sensing material is located between two metal electrodes, and a third metal electrode, which is usually platinum, is used for the heating of the sensor device. There are numerous methods by which such sensors can be realized. Figure 3.5 shows traditional gas sensor-electrode geometries.To make measurements on a semiconductor gas sensing material it is possible to use a compressed sintered or unsintered pellet with metal contacts on each face.
