An approach for training of temperature cycled metal oxide semiconductor gas sensors to monitor food quality is presented. A setup including various gas sensors and a GC-MS is used to measure the ...

Gas sensor array (GSA) data usually has high-dimensional features and a small sample size. When a classifier is directly used for GSA data classification, it is prone to overfitting and has a high ...

Environmental pollution is a major concern, particularly in modern cities, due to its significant effects on human health and the global economy. These pollutants must be continuously monitored to ...

The gas sensor, based on a p–n heterojunction structure, was fabricated by vertically stacking a nanometer-thick layer of p-type cobalt phthalocyanine (CoPc) on a solution-processed n-type ...
