heal.abstract	A comparative study on the response of tin and indium oxide thin sputtered films to different reducing gases is presented. The operation of the sensors is based on the Seebeck effect. Platinum has been deposited on half of the films; thus as the rates of gas reaction on the two halves of the films are expected to be different (inducing a temperature gradient), a Seebeck voltage is developed as the response signal. Different responses experimentally observed for tin and indium oxide sensors are qualitatively explained with the aid of the well established theory of chemisorption of reducing gases on metal oxides and the different electronic properties of tin and indium oxide films. The target gases used were 2000 ppm CO, 10,000 ppm CH4 and 26 ppm C2H5OH diluted in zero-grade air (ZGA).	en
