What is meant by e-nose?
What is meant by e-nose?
An electronic nose is an electronic sensing device intended to detect odors or flavors. The expression “electronic sensing” refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems.
What are electronic noses and biosensors?
Electronic noses are bioinspired instruments that mimic the biological sense of smell. They are based on the use of gas sensors or biosensors combined with pattern recognition methods.
Why there is a need of using e-nose?
Electronic noses have been used for the evaluation of sample headspace or the liquid directly with different purposes. Others have used the electronic nose for the discrimination between bacteria and/or the discrimination of the production of VOCs of different bacterial strains into the sterile field.
How does electronic tongue work?
Electronic tongue (e-tongue) is a novel technology that is used for taste evaluation of foods. Its working principle includes the conversion of food taste molecular information into visual taste information, which can easily be measured by mathematical optimizations (Wardencki et al., 2013).
Do electronic noses exist?
Several instruments known as electronic noses have been developed, which typically consist of an array of gas-sensitive semi-conductors connected to an appropriate pattern-recognition system. Electronic noses have the capability to detect complex odours.
Is olfactory a smell?
The olfactory system, or sense of smell, is the sensory system used for smelling (olfaction). Olfaction is one of the special senses, that have directly associated specific organs….

Can we create smell?
In 2005, researchers from the University of Huelva developed XML Smell, a protocol of XML that can transmit smells. The researchers also developed a scent-generating device and worked on miniaturising its size.
Can machines detect smell?
Machine olfaction is the automated simulation of the sense of smell. One type of proposed machine olfaction technology is via gas sensor array instruments capable of detecting, identifying, and measuring volatile compounds. …
What is a taste sensor?
A taste sensor is required to exhibit global selectivity so that it responds consistently to the same taste similarly to the human tongue. Toko’s group at Kyushu University, Japan, we have successfully developed taste sensors based on an artificial lipid membrane that consistently responds to similar taste.
Is there any smell sensor?
Each of the odor sensors, such as MOS or QCM sensors, has characteristics that respond to different odors. When many odor sensors are combined in one system, their ability to detect an odor is increased.
Who invented e-nose?
Jing Li, inventor of NASA’s E-Nose, or electronic nose, device inspects sensor array chips inside the device for COVID-19 detection.
Where is sense of smell in brain?
Olfactory Cortex
The Olfactory Cortex is the portion of the cerebral cortex concerned with the sense of smell. It is part of the Cerebrum. It is a structurally distinct cortical region on the ventral surface of the forebrain, composed of several areas. It includes the piriform lobe and the hippocampal formation.
What are electronic noses and electronic tongues?
Electronic noses (e-noses) and electronic tongues (e-tongues) crudely mimic the human smell and taste sensors (gas and liquid sensors) and their communication with the human brain.
What are the advantages of e-nose and E-tongue?
E-nose and e-tongue are also suitable for both in-line and off-line measurements, which are very useful in monitoring food processing and detecting the end product quality. The user of e-nose and e-tongue need to strictly control sample preparation, sampling, and data processing.
What is e-nose technology?
An electronic nose (e-nose) is a gas sensor array that gives fingerprint response to specific volatiles, which then can be used by pattern recognition algorithms, such as artificial neural network (ANN), to perform discrimination and classification.
What is e-nose or e-Tongue combining pattern recognition algorithms?
Overall, e-nose or e-tongue combining pattern recognition algorithms are very powerful analytical tools, which are relatively low-cost, rapid, and accurate. E-nose and e-tongue are also suitable for both in-line and off-line measurements, which are very useful in monitoring food processing and detecting the end product quality.
