Abstract: To integrate the ceramic Pt/alumina catalyst on micro-hotplate of micro-thermoelectric hydrogen sensor (micro-THS), a dispenser technique was used in this study. This micro-THS with the Pt/alumina catalyst is capable of sensing wide range hydrogen concentration of 50 ppm to 3 % at room temperature. For hydrogen/air mixture gas of 50 ppm, voltage signal is measured to be 0.03 mV at room temperature.
