Sensor discriminators and methods for detecting electrical property changes in a metal organic framework
| DWPI Title: System for detecting presence and/or concentration of gaseous substance in metal organic framework, has discriminator output comprising comparison of discrimination pulse to simulation pulse and indicative of presence and/or concentration of gaseous substance |
| Abstract: A sensor discriminator for detecting a gaseous substance includes a power source, a discrimination module, a sensor simulator that simulates a metal organic framework under at least one simulation condition, a simulation circuitry electrically coupling the sensor simulator to the power source and the discrimination module, and a discriminator circuitry that electrically couples the power source and the discrimination module to a gas capture probe. The discrimination module compares a discrimination pulse and a simulation pulse from the power source after the discrimination pulse passes through a metal organic framework of the gas capture sensor and the simulation pulse passes through a simulation component of the sensor simulator. The discrimination module causes a discriminator output that includes the comparison of the discrimination pulse to the simulation pulse. An electrical property of the discrimination pulse depends on an electrical parameter of the metal organic framework that is augmented by the gaseous substance. |
| Use: System for detecting a presence and/or a concentration of a gaseous substance in a metal organic framework. |
| Advantage: The system's design, especially the use of discrimination pulses and comparison of simulation and actual readings, ensures that the sensor can distinguish between different types of gaseous substances and accurately quantify their concentrations. This increases the specificity of the sensor for particular gases. The system can be adjusted and adapted to detect various gases under different environmental conditions, making it versatile for use in different applications, such as industrial emissions monitoring, environmental monitoring, or even healthcare-related applications where detecting certain gases is important. |
| Novelty: System comprises a metal organic framework configured to exhibit at least one electrical property responsive to exposure to a gaseous substance, a sensor discriminator (200) for detecting the gaseous substance, the sensor discriminator electrically coupled to the metal organic framework and comprising: a power source, a discrimination module comprising a comparator, and a sensor simulator comprising at least one simulation component, where the at least one simulation component simulates the metal organic framework under at least one simulation condition, at least one processor, and at least one memory, the at least one memory comprising a non-transitory computer-readable medium having computer-executable instructions stored. |
