Applications and Advances in Electronic-Nose Technologies
Sensors, 2009
Electronic-nose devices have received considerable attention in the field of sensor technology during the past twenty years, largely due to the discovery of numerous applications derived from research in diverse fields of applied sciences. Recent applications of electronic nose technologies have come through advances in sensor design, material improvements, software innovations and progress in microcircuitry design and systems integration. The invention of many new e-nose sensor types and arrays, based on different detection principles and mechanisms, is closely correlated with the expansion of new applications. Electronic noses have provided a plethora of benefits to a variety of commercial industries, including the agricultural, biomedical, cosmetics, environmental, food, manufacturing, military, pharmaceutical, regulatory, and various scientific research fields. Advances have improved product attributes, uniformity, and consistency as a result of increases in quality control capabilities afforded by electronic-nose monitoring of all phases of industrial manufacturing processes. This paper is a review of the major electronicnose technologies, developed since this specialized field was born and became prominent in the mid 1980s, and a summarization of some of the more important and useful applications that have been of greatest benefit to man.
Developments in Electronic Nose Systems
TJPRC, 2013
Electronic nose has received considerable attention of the research scholars and industries because of its wide range of applications and the innovations done in the field of sensor technology. E-nose technology has quietly advanced during the last twenty years. Commercial models equipped with sensor arrays came to market in the mid-1990s, and today they're being used in every aspects of our life e.g. food, health, pharmaceuticals, environment monitoring, manufacturing, cosmetics, and packaging industries etc. In this paper we have discussed some of the research works and the developments done in electronic nose systems during last few years.

Electronic Nose and Its Applications: A Survey
International Journal of Automation and Computing, 2019
In the last two decades, improvements in materials, sensors and machine learning technologies have led to a rapid extension of electronic nose (EN) related research topics with diverse applications. The food and beverage industry, agriculture and forestry, medicine and health-care, indoor and outdoor monitoring, military and civilian security systems are the leading fields which take great advantage from the rapidity, stability, portability and compactness of ENs. Although the EN technology provides numerous benefits, further enhancements in both hardware and software components are necessary for utilizing ENs in practice. This paper provides an extensive survey of the EN technology and its wide range of application fields, through a comprehensive analysis of algorithms proposed in the literature, while exploiting related domains with possible future suggestions for this research topic.
Current and Future Research of E-Nose(Electronic Nose
Over last decade electronic sensing or e-sensing becomes an important technology from both of technical and commercial point of view which refers to the capability of reproducing human senses using sensor arrays and pattern recognition system. An electronic nose is such an instrument which consists of mechanism for identification of chemical detection such as an array of electronic sensors and a mechanism of pattern recognition. This paper highlights the significant researches of Electronic nose which are being performed currently and at the same time how can we use it in the future more effectively. Introduction-An electronic nose is a device intended to detect odors or flavors. It is an
Multidisciplinary Applications of Electronic Noses to Monitor Environment and Health
Aroma, flavors and fragrances are due to extrinsic and intrinsic factors, reveals the real-time status of the object. There are attempts to develop the mimic of biological noses or advance forms by the scientists time to time. A few devices developed are more advanced than biological system but specific to certain trait only. The specificity of these devices is quite helpful in agriculture, biomedical, cosmetics, environmental, food, defense and research activities than biological noses. The electronic nose is a cheap and easy technique to decipher the shelf-life of various products in markets, even to detect the hazardous or poisonous gas where biological sniffer is not possible. Generally, it is a three-component device namely sample delivery, detecting and computing system. Currently, multi-tech devices are in-use to identify individual components of a gas mixture by a merger with conventional analytical instruments. For better sensitivity and resolution still, there is a look at the artificial system with similar or better performance than biological noses in different environmental conditions.
Electronic noses and their applications
1995
Electronic/artificial noses are being developed as systems for the automated detection and classification of odors, vapors, and gases. An electronic nose is generally composed of a chemical sensing system (e.g., sensor array or spectrometer) and a pattern recognition system (e.g., artificial neural network). We are developing electronic noses for the automated identification of volatile chemicals for environmental and medical applications. In this paper, we briefly describe an electronic nose, show some results from a prototype electronic nose, and discuss applications of electronic noses in the environmental, medical, and food industries.

Context: Quality Control (QC) has been constantly an essential concern in many fields like food industry production, medical drugs, environmental protection, and so on. An odor or flavor, as a global fingerprint, can be implemented as a non-invasive mechanism for quality assurance. This computer-based approach can assure accurate detection and precise identification of the product quality or manufactured goods. Objective: This paper aims to achieve a systematic review about e-nose by introducing the achievements made by researchers in this area, to summarize their findings, to provide motivations and challenges to new researchers in the field of e-nose. Methods: The articles that were being utilized in the e-nose field were systematically achieved using three search engines: The online library of IEEE Explore, Web of Science and Science Direct for time span of 7 years (from 2013 to 2020). Both medical literature reviews and technical reviews were considered in the criteria of the re...
The development of an electronic ‘nose’ for industrial and environmental applications
Sensors and Actuators B: Chemical, 1995
The electronic nose detailed in this paper deals entirely with a conducting polymer sensor system. This works on the principle of 12 different sensors monitoring a complex vapour in the headspace above a sample. The ability of any system to mimic the human nose depends primarily on the sensor characteristics. Therefore, most of the development work has been on the sensor materials and the fabrication process. The range of sensors described exhibits significantly different responses to most vapours tested. Therefore, it has been shown using 12 of these sensors that very good discrimination can be achieved between very similar samples over a wide range of products. The complete system is easy to use in the laboratory, and software has been developed to enable the complex data to be analysed and presented in a simple summary form.
Applications and Technology of Electronic Nose for Clinical Diagnosis
Rapid advances in sensor technologies have facilitated the development of high-performance electronic noses that can detect and discriminate volatile compounds in situ. The research and development of electronic noses has resulted in a new qualitative and semi-quantitative detection approach in the field of clinical diagnostics. Electronic noses have a clear potential to be a non-invasive, simple and rapid but above all accurate early diagnostic screening tool. This review collates existing knowledge of recent advances in electronic nose technologies and applications.
