Odours and flavours identified with hybrid modular sensor systems1

Electronic Nose: Current Status and Future Trends

“…14,15 Sensors with different transducer principles will be selective for different classes of substances and can therefore often provide additional information. Hence, in recent years the original sensor types used for electronic noses were not only enhanced but complemented by other technologies introduced in this field.…”

Correspondences between olfactometry, analytical and electronic nose data for 10 indoor paints

“…It displays rapid response without having to wait for stabilization of the steady-state signal. Few other studies have used this feature but they found an improvement in the discrimination level with other kind of sensor array [28,29].…”

“…sensor technologies) is needed, as each only uses a subset of the initial space [31,32]. The use of hybrid electronic nose has already proved to improve considerably complex samples discrimination [29]. Furthermore, current sensors display a lack of sensitivity compared to the quantum efficiency of olfactory receptors [33].…”

Detection of odour emissions from a composting facility using a QCM sensor array

“…Ulmer et al [12] used a polymer-coated quartz microbalance as one of their sensors to identify odours and flavours. They optimised the quantitative analysis of known gases mixtures.…”
