It appears now more clearly than in Figure 4 that every sensor/analyte couple has a distinct chemoresistive imprint suitable for VOC discrimination. This is also highlighted by Figure 6 (right), which presents the PC1–PC2 map for an array of four sensors successively exposed to the four selected VOC after PCA data processing.

Chemoresistive sensors for gases and volatile organic compounds (VOC) base their working principle on the variation of their electrical resistivity when they come into contact and react with specific substances in the surrounding environment. So, it is possile to measure the amount of gas or VOC near the sensor by simply measuring its proportional resistance. This kind of sensors, mainly ...

1 VOC Sensors What are VOCs VOC is an abbreviation for Volatile Organic Compounds and a collective term for gaseous carbonaceous substances. Depending on how high the concentration of these substances in the ambient air is, we can perceive them by smelling them with our nose. On average, a person inhales about 15 kg of air per day, 80% of it indoors. Outside air quality is routinely ...

In last two decades common materials for developing of VOC chemoresistive sensors were based on metaloxides [5,6]. Even, making a great progress with several commercial devices on market, these materials have some limitations such as high temperature requirement, lack of high gas/vapour sensitivity, low selectivity and tuning ability that are often needed for development of sensing ...

Different grades of chemically functionalized carbon nanotubes (CNT) have been processed by spraying layerbylayer (sLbL) to obtain an array of chemoresistive transducers for volatile organic compound (VOC) detection. The sLbL process led to random networks of CNT less conductive, but more sensitive to vapors than filtration under vacuum (bucky papers). Shorter CNT were also found to be more ...
