Potential of Metal Reactive Oxides for Development of 4H-Silicon Carbide-based Metal-Oxide- Semiconductor Gas Sensor

The escalating demand in automotive industry nowadays has evoked civic awareness towards environmental issues brought by the exhaust emissions through fossil fuel combustion engine or hydrogen leak in fuel cell vehicles. Metal-oxide-semiconductor (MOS)-based gas sensors that were able to monitor the changes of oxygen and hydrogen leak were required. By replenishing the conventional silicon-MOS-...

Olfaction Metal Oxide Semiconductor Gas Sensors and Neural Networks

Primitive mobile life forms, and the mobile cells of higher animals, derive their motivation and direct their navigation by chemical senses. In the simplest cases these creatures are hard-wired to swim toward nutrient concentration gradients, and to swim against irritant concentration gradients. The vestiges in humans of the sometimes extremely sensitive, selective, and differential chemical se...

Metal Oxide Gas Sensor Drift Compensation Using a Dynamic Classifier Ensemble Based on Fitting

Sensor drift is currently the most challenging problem in gas sensing. We propose a novel ensemble method with dynamic weights based on fitting (DWF) to solve the gas discrimination problem, regardless of the gas concentration, with high accuracy over extended periods of time. The DWF method uses a dynamic weighted combination of support vector machine (SVM) classifiers trained by the datasets ...

A Customized Metal Oxide Semiconductor-Based Gas Sensor Array for Onion Quality Evaluation: System Development and Characterization

A gas sensor array, consisting of seven Metal Oxide Semiconductor (MOS) sensors that are sensitive to a wide range of organic volatile compounds was developed to detect rotten onions during storage. These MOS sensors were enclosed in a specially designed Teflon chamber equipped with a gas delivery system to pump volatiles from the onion samples into the chamber. The electronic circuit mainly co...
