Electronic Nose Global Market Report 2025

The electronic nose market size has grown rapidly in recent years. It will grow from $26.98 billion in 2024 to $30.4 billion in 2025 at a compound annual growth rate (CAGR) of 12.6%. The growth in the historic period can be attributed to growing awareness of environmental monitoring and pollution control, a growing focus on food safety and quality control, an increasing demand for e-nose sensing devices, a surge in the use of sensors, and an increasing demand for electronic noses in air quality monitoring and pollution control.

The electronic nose market size is expected to see rapid growth in the next few years. It will grow to $50.46 billion in 2029 at a compound annual growth rate (CAGR) of 13.5%. The growth in the forecast period can be attributed to growing awareness of environmental pollution, increasing emphasis on environmental surveillance, growing scope for the use of e-noses in the detection of food authenticity, demand need for pollution monitoring, increasing environmental monitoring, and odor control. Major trends in the forecast period include research institutions and technological innovation, AI and e-nose technology, e-nose technologies, innovative electronic nose (e-nose) technology, and advanced detection technologies.

The forecast of 13.5% growth over the next five years reflects a modest reduction of 0.6% from the previous estimate for this market. This reduction is primarily due to the impact of tariffs between the US and other countries. This is likely to directly affect the US through shortages of gas sensor arrays and machine learning processors from Switzerland and South Korea, hindering development of air quality monitoring systems. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The growth of the automotive industry is expected to drive the expansion of the electronic nose market in the coming years. The automotive industry encompasses the design, development, manufacturing, marketing, and sale of motor vehicles, including cars, trucks, motorcycles, and their components. This industry's growth is fueled by the increasing demand for electric vehicles (EVs) and the expansion of global markets. The rising demand for EVs is largely driven by growing environmental concerns and government incentives for greener transportation solutions. Electronic noses in the automotive sector are used to detect and analyze odors, improve cabin air quality, identify material off-gassing, and support quality control during manufacturing. For instance, in March 2024, the European Automobile Manufacturers' Association, a Belgium-based industry group, reported strong growth in the European Union automotive market, with sales increasing by 13.9% in 2023 compared to 2022, reaching a total of 10.5 million units. As a result, the growth of the automotive industry is expected to propel the electronic nose market.

Key players in the electronic nose market are focusing on adopting sensor-based technologies, such as commercial metal semiconductor oxide (MOS) sensors, to improve detection accuracy, sensitivity, and broaden applications across different industries. Commercial MOS sensors are gas sensors that detect and analyze volatile compounds by measuring changes in electrical resistance when gases interact with metal oxide materials. For example, in January 2024, the Department of Electrical Engineering at the National Kaohsiung University of Science and Technology in Taiwan developed an electronic nose capable of identifying coffee aromas with 98% accuracy. This device uses eight commercial MOS sensors to detect specific aroma-related gases, analyzing roasted and brewed coffee from different varieties and origins. An AI algorithm then processes the data, enhancing the classification of coffee based on scent detection.

In August 2023, Aino's, Inc., a US-based biotech company specializing in AI-powered electronic nose technology, partnered with Nisshinbo Micro Devices. This collaboration combines Aino's AI-driven digital nose, supported by over 50 patents, with Nisshinbo's expertise in electronic and microwave devices. Nisshinbo Micro Devices Inc., based in Japan, develops and manufactures electronic devices and microwave products, further advancing the potential of AI-driven scent technology.

An electronic nose is a device equipped with sensor arrays to detect and identify odors or volatile compounds in the air, mimicking the human sense of smell. It captures the chemical signatures of various scents and analyzes them using pattern recognition algorithms. Electronic noses are widely used to identify and measure odors that may be harmful or indicative of specific conditions.

The main types of electronic noses include embedded sensors and portable devices. Embedded sensors are integrated sensing components that detect and analyze volatile compounds in real time, supporting applications such as air quality monitoring, food safety, and disease detection. These devices utilize various technologies, including metal oxide semiconductor sensors (MOS), quartz crystal microbalance (QCM), conducting polymers (CP), surface acoustic wave (SAW), and other advanced technologies. Electronic noses are applied across industries such as food and beverage, healthcare, environmental monitoring, security and defense, among others. The primary end users include industrial, commercial, and residential sectors.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp escalation of U.S. tariffs and resulting trade tensions in spring 2025 are significantly affecting the electrical and electronics sector. Key components such as semiconductors, display panels, and rare-earth metals crucial for batteries and motors are now facing heavy duties. Consumer electronics companies are seeing profit margins shrink, as fierce competition makes it difficult to pass on rising costs to consumers. At the same time, industrial electronics firms are experiencing project delays due to shortages of tariff-impacted parts like printed circuit boards. In response, businesses are shifting assembly operations to tariff-exempt nations, building up inventory reserves, and redesigning products to reduce reliance on restricted materials.
