摘要： 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).
摘要翻译：本发明提供新颖的氢传感器及其制造方法。在一些实施方案中，这样的新型氢传感器是连续范围的氢传感器，其包括在电阻表面上排列为纳米线或二维形状的Pd-Ag纳米颗粒。这种连续范围的氢传感器能够在宽的温度范围内测量宽范围的氢气浓度。与现有氢传感器不同，在一定的氢浓度下，电阻的变化很大，本发明的连续范围氢传感器在宽范围的氢浓度下连续地改变电阻。这种连续变化随氢气浓度而变化缓慢，并且是可预测的，使得连续范围氢传感器可用于在宽范围的温度（例如-40℃）下连续测量从几ppm到40,000ppm水平或更高的氢浓度至+ 150℃）。

摘要： The present invention provides for variable-range hydrogen sensors (502) and methods for making same. Such variable-range hydrogen sensors (502) comprise a series of fabricated Pd-Ag (palladium-silver) nanowires (106, 301) - each wire of the series having a different Ag to Pd ratio-with nanobreakjunctions (302) in them and wherein the nanowires (106, 301) have predefined dimensions and orientation. When the nanowires (106, 301) are. exposed to H2, their lattace swells when the H2 concentration reaches a threshold value (unique to that particular ratio of Pd to Ag). This causes the nanobreakjunctions (302) to close leading to a 6-8 orders of magnitude decrease in the resistance along the length of the wire and providing a sensing mechanism for a range of hydrogen concentrations.
