Abstract

The MEMS thin film heater was prepared by all dry processes and the heating properties of this heater were evaluated. The MEMS heaters were heated up to 400°C at consumed power of a few ten mW. The consumed power for heating was dependent on the heater area and the membrane size. Furthermore, 40 ppm ethanol gas was detected in smaller size and at lower-power consumption by the MEMS gas sensor utilizing this MEMS heater than by the conventional bulk gas sensor.
