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

Pure SnO 2 is widely used to detect VOC gases due to its high stability. Unfortunately, there
is a problem of poor selectivity, especially for gases such as ketones and alcohols, which …

Poor selectivity of metal oxide semiconductor (MOS) gas sensors (toward volatile organic
compounds, VOCs) poses a significant challenge for their applications in the emerging …

The temperature modulation method is used to improve the selectivity of sensor, but there
are still some deficiencies in the gas mixture recognition. The dynamic response law is …

Sharp operating temperature fluctuations in an analyte-exposed gas sensor result in
temporal responses containing considerable amounts of extractable analyte-related …

Despite the successful detection performance of electronic nose in laboratories, they face
challenges for use in the industry due to their accuracy reduction resulted from variable …

We report, for the first time, discriminating among complex odors using a single generic tin
oxide gas sensor. The sensor heater is biased with high magnitude voltage impulses of …

We present an active sensing method for quantitative analysis of gas mixtures using metal-
oxide (MOX) chemical sensors. The method allows a MOX sensor to adapt its operating …

Data processing methods commonly used in conjunction with the array-and quasi-array-
based gas identification systems generally include a dimension reduction followed by …

This paper presents a flexible printed sensor to detect two different magnitudes: toluene
content and relative humidity. This device has been manufactured by using two printing …
