    Abstract

    In this paper, thermo-resistive platinum (Pt) thin film sensor, which was produced using Micro Electro Mechanical Systems (MEMS) fabrication techniques, is proposed. The sensor design incorporated resistor elements that would facilitate the temperature-resistance characteristics and mechanisms of Pt based thin film thermo-resistors. Especially, this paper reports the characteristics of a new differential Pt thin film hydrogen gas sensor. The fabricated hydrogen sensor detected the concentration of hydrogen gas in the air from 2% to 10%. It was possible to achieve the correct the heat transfer with this new differential Pt thin film hydrogen gas sensor. The characteristics of sensor's output are higher than conventional ones that we developed.
