Abstract: A system and method is disclosed for providing a hydrogen sensor optimally comprising a multicore optical fiber strain sensor, interacting with a kinematic or mechanical amplification assembly, which is in turn connected to a responsive hydrogen storage material. In general, the sensor comprises any system or method whereby hydrogen concentration is derived from measuring the strain associated with crystallographic change and/or displacement associated with a hydrogen storage material as it takes up and gives off hydrogen.

Abstract: A multi-component fluid composition and concentration sensor system and method. The system can be configured with multiple sensing elements whereby each specifically responds to different combinations and concentrations of multiple fluid component mixtures. Because these responses can be captured and committed to a lookup table during an initial calibration sequence, subsequent measurements of unknown mixtures of the same gases will match known states found in the lookup table and the fluid concentrations can be deduced. The number of sensing elements with unique responses to the fluid mixtures should equal the number of unknown fluids that are active on the sensing surfaces, similar to how solving for multiple variables requires no fewer equations than there are unknowns, i.e. “3 equations and 3 variables.
