This paper provides an overview of recent developments in the field of volatile organic
compound (VOC) sensors, which are finding uses in healthcare, safety, environmental …

The chemical signatures of volatile organic compounds (VOCs) in humans can be utilized
for point-of-care (POC) diagnosis. Apart from toxic exposure studies, VOCs generated in …

Air pollution is a major concern for public health and urban environments. Conventional air
pollution monitoring systems install a few highly accurate, expensive stations at …

Inherent variability of chemical sensors makes it necessary to calibrate chemical detection
systems individually. This shortcoming has traditionally limited usability of systems based on …

Domain adaptation algorithms are useful when the distributions of the training and the test
data are different. In this paper, we focus on the problem of instrumental variation and time …

Since their inception, biosensors have frequently employed simple regression models to
calculate analyte composition based on the biosensor's signal magnitude. Traditionally …

The present review evaluates the key modules of the electronic nose, a biomimetic system,
with specific examples of applications to industrial emissions monitoring and measurement …

Electronic nose (enose, EN) and electronic tongue (etongue, ET) have been designed to
simulate human senses of smell and taste in the best possible way. The signals acquired …

In recent decades, with the rapid development of artificial intelligence, data mining, and
cloud computing, new chemometric methods have sprung up and become one of the fastest …

Electronic noses, or e-noses, refer to systems powered by chemical gas sensors, signal
processing, and machine learning algorithms for realizing artificial olfaction. They play a …
