Model Based Analysis

Researchers have successfully prepared reflection-mode hydrogen sensor by coating Palladium (Pd) alloy in the end of the fiber and it has been proved to be in good effect. Characteristics of the hydrogen sensors are influenced by several factors, such as thickness of thin film, substrate, light wavelength and the film material, etc. For best performance, an optical model of reflection-mode fiber hydrogen sensor is established. The effecting law of each factor is analyzed and discussed through model-based simulation method. The results can provide credible design methods for the reflection-mode fiber hydrogen sensor.

AbstractIn order to extend the dynamic range of a hydrogen sensor with a metal-insulator-semiconductor (MIS) type structure, Pd-Cr and Pd-Ni alloy gated samples were studied. The PdCr gated sample shows quite stable and reproducible response, and could measure hydrogen concentrations from 100 to 50, 000 ppm. While the Pd-Ni gated sample shows turn-on/off response drift, this drift is probably due to the presence of oxygen on the surface of the insulator and the formation of metal hydride. Furthermore, the effect of oxygen on the sensors response was investigated; oxygen may deplete protons from the metal/insulator interface and could reduce the sensor's response.
