Title (EN) CONTINUOUS-RANGE HYDROGEN SENSORS
(FR) SONDES D'HYDROGENE A PLAGE CONTINUE
Abstract: front page image
(EN)The present invention provides for novel hydrogen sensors and methods for making same. In some embodiments, such novel hydrogen sensors are continuous-range hydrogen sensors comprising Pd-Ag nanoparticles arrayed as nanowires or two-dimensional shapes on a resistive surface. Such continuous-range hydrogen sensors are capable of measuring a wide range of hydrogen gas concentration over a wide temperature range. Unlike existing hydrogen sensors that experience a large change in resistance at a certain hydrogen concentration, the continuous-range hydrogen sensor of the present invention changes resistance continuously over a broad range of hydrogen concentration. This continuous change varies slowly with hydrogen concentration and is predictable such that the continuous-range hydrogen sensor can be used to measure hydrogen concentration continuously from a few ppm to 40,000 ppm level or higher over a broad range of temperatures (e.g., -40°C to +150°C).
(FR)La présente invention concerne des sondes d'hydrogène et leurs procédés de fabrication. Pour certains modes de réalisation, ces sondes sont à plage continue, comprenant des nanoparticules Pd-Ag en réseaux de nanofils ou de structures bidimensionnelles sur une surface résistive. Ces sondes permettent de mesurer de grandes plages de teneurs en hydrogène gazeux, dans une grande plage de températures. A la différence des sondes d'hydrogène qui connaissent une grande variation de résistance à certains niveaux d'hydrogène, la résistance de la sonde de l'invention varie de façon continue dans une grande plage de teneurs. Cette variation continue, qui évolue lentement avec teneur en hydrogène, est prévisible, ce qui permet d'utiliser la sonde pour la mesure des teneurs en hydrogène, en continu depuis quelques ppm jusqu'à 40.000 ppm au moins, dans une grande plage de températures, et notamment de -40 °C à +150 °C.
