Metal-oxide sensors are made up of semiconducting metal oxides like tin dioxide (SnO2), zinc oxide (ZnO), and tungsten oxide (WO3). The electrical conductivity of synthetic metal oxides is different when exposed to different gases. This makes them highly sensitive in the detection of volatile organic compounds (VOCs) emitted by a variety of foods, beverages, or environmental samples.
Metal-oxide sensors became the technical solution for the majority of deployments of electronic nose in a host of applications in industries. In May 2024, researchers developed a zinc oxide (ZnO)-based chemiresistive gas sensor capable of detecting carbon monoxide (CO) at low temperatures. The sensor demonstrated around 8% sensitivity at 50°C with a rapid response time of approximately 10 seconds. This enhanced performance is attributed to the interaction between CO molecules and oxygen vacancies in ZnO, improving charge carrier movement.
In terms of application, food and beverage segment is estimated to contribute the highest market share of 38% in 2025. This is because electronic noses are increasingly being adopted for quality testing and process monitoring in the food and beverage industry.
Moreover, electronic noses can discriminate between subtle odor characteristics to distinguish between similar food items or batches. Their use is growing for applications like freshness grading of meat and dairy, authenticity testing of wine, brewing and distillation monitoring. The demand from food and beverage manufacturers makes it currently the largest application segment.
In terms of end user, industrial segment is estimated to contribute the highest market share of 54.3% in 2025. Electronic nose systems are commonly installed by various process industries to monitor air/gas quality at different points. The demand from power plants, oil/gas refineries, pharmaceutical manufacturing, chemical processing, and other major industries has propelled the industrial end user segment to dominance. Its large size installations also contribute significantly to industry revenues.
