In this review, the different important parameters having significant effects on the sensing
behavior of semiconductor metal oxide (SMO) based chemiresistive gas sensors have been …

The biological olfactory system is the sensory system responsible for the detection of the
chemical composition of the environment. Several attempts to mimic biological olfactory …

Gas sensors have made great progress in gas sensing performances (such as response,
sensitivity, detection limit and response speed), but they are generally affected by …

Signal and data processing are essential elements in electronic noses as well as in most
chemical sensing instruments. The multivariate responses obtained by chemical sensor …

In the present brief review modern views on the reasons of time instability of gas sensors
parameters, as well as approaches, which could be used for the improvement of this …

A method for online decorrelation of chemical sensor signals from the effects of
environmental humidity and temperature variations is proposed. The goal is to improve the …

Abstract Machine learning (ML) methodologies were applied to detect and discriminate five
indoor volatile organic compounds (VOCs) such as benzene, xylene, toluene, formaldehyde …

Anti-drift is an emergent and challenging issue in sensor-related subjects. In this paper, we
propose to address the time-varying drift (eg electronic nose drift), which is sometimes an ill …

The COVID-19 pandemic has attracted numerous research studies because of its impact on
society and the economy. The pandemic has led to progress in the development of …

One of the obstacles to the wider practical use of the multisensor systems for gas and liquid
analysis—electronic noses and tongues, is the limited temporal validity of the multivariate …
