Breath analysis is a relatively recent field of research with much promise in scientific and
clinical studies. Breath contains endogenously produced volatile organic components …

Gas recognition is essential in an electronic nose (E-nose) system, which is responsible for
recognizing multivariate responses obtained by gas sensors in various applications. Over …

A neuromorphic module of an electronic nose (E‐nose) is demonstrated by hybridizing a
chemoresistive gas sensor made of a semiconductor metal oxide (SMO) and a single …

Support vector machine recursive feature elimination (SVM-RFE) is a powerful feature
selection algorithm. However, when the candidate feature set contains highly correlated …

An electronic nose (e‐nose) is a device that can detect and recognize odors and flavors
using a sensor array. It has received considerable interest in the past decade because it is …

Currently, a small number of diseases, particularly cardiovascular (CVDs), oncologic (ODs),
neurodegenerative (NDDs), chronic respiratory diseases, as well as diabetes, form a severe …

The research and development of new electronic-nose applications in the biomedical field
has accelerated at a phenomenal rate over the past 25 years. Many innovative e-nose …

The human olfactory system remains one of the most challenging biological systems to
replicate. Humans use it without thinking, where it can measure offer protection from harm …

In human exhaled breath, more than 3000 volatile organic compounds (VOCs) are found,
which are directly or indirectly related to internal biochemical processes in the body …

Electronic noses have potential applications in daily life, but are restricted by their bulky size
and high price. This review focuses on the use of chemiresistive gas sensors, metal-oxide …
