Sensor stability is defined as the ability to maintain a relatively stable and repeatable signal
over a sufficient period. Long-term stability for gas sensors is an essential capability for …

Electronic noses (e-noses) are devices based on combining different gas sensors'
responses to a given sample for identifying specific odor fingerprints. In recent years, this …

With the rampant drug crime, the detection of drug-producing chemicals has put forward the
great demand of multi-type and multi-concentration on-line rapid detection. The rapid …

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 …

The extremely widely applied metal oxide semiconductor (MOS) gas sensors suffer from
underdeveloped selectivity, and dynamic measurement methods are expected to solve this …

Gas detection and discrimination have been, until recently, sensors-specific, with different
sensors and techniques used for each of the gases. In this work, we describe a novel …

The chemresistive sensing process derives from the interfacial interactions between the
gaseous molecule and the sensing material's surface. However, the deeper understanding …

With the development of science and technology, gas sensors have gradually expanded to
many vertical fields. However, each application requires different technical requirements for …

Two microchips, each with four identical microstructured sensors using SnO 2 nanowires as
sensing material (one chip decorated with Ag nanoparticles, the other with Pt nanoparticles) …

The metal oxide semiconductor sensors to quantify mixed gas components has been still
difficult due to the poor selectivity although it has many advantages on application. To …
