Indoor air pollution (IAP) is a serious threat to human health, causing millions of deaths each
year. A plethora of pollutants can result in IAP; therefore, it is very important to identify their …

Breath analysis is an attractive strategy that holds tremendous potential to achieve non-
implantable physical health management enabled by flexible humidity sensors for breathing …

Artificial scent screening systems (known as electronic noses, E‐noses) have been
researched extensively. A portable, automatic, and accurate, real‐time E‐nose requires both …

To improve the poor selectivity of a semiconductor gas-sensor system, an array of sensors
can be utilized. However, this increases the system's size and power consumption. To …

Artificial olfaction, ie, e‐nose, plays a critical function in robotics by mimicking the human
olfactory organ that can recognize different smells that correlate with a range of fields …

In this work, a sensor array comprised four sensors has been employed to detect 11 types of
mixtures of nitrogen dioxide (NO 2) and carbon monoxide (CO), with concentration varying …

Real-time monitoring of health threatening gases for chemical safety and human health
protection requires detection and discrimination of trace gases with proper gas sensors. In …

Inspired by biological noses, their electronic counterparts ie e-noses are designed to imitate
them by detecting and identifying surrounding gases and volatile compounds through the …
