Breakup by Type

• Embedded Sensors
• Portable Devices

The deployment of embedded sensors is geared towards integration into larger systems for continuous monitoring and automation. These sensors are put to use in industrial applications, food processing lines, and environmental monitoring setups, where real-time data collection and process control become essential. Embedded sensors prove to be efficient for quality control, air quality monitoring, and detection of hazardous agents as they give stable and accurate readings.

Portable devices, on the other side, have been equipped for flexibility and mobility. Operating in handheld or compact form factors, portable devices have been gradually accepted for applications of hazardous fieldwork, entry-point inspection, and fast diagnostics. The portability of these devices allows for abundance evaluation, odor control testing, and authenticity checking, especially used in agriculture, food retail, and pharmaceuticals. For instance, respiratory diseases like asthma, chronic obstructive pulmonary disease (COPD), and lung cancer can change the composition of volatile organic compounds (VOCs) in breath. Most of these portable devices are backed-up by cloud-connected platforms and AI-based software for real-time scent detection and data analysis. In line with the evolution of miniaturized sensor technology, portable electronic noses are becoming advanced, cheap, and easily available, thus promoting broader market acceptance.

Breakup by Technology Type

• Metal Oxide Semi-Conductor Sensors (MOS)
• Quartz Crystal Microbalance (QCM)
• Conducting Polymers (CP)
• Others

Metal Oxide Semiconductor (MOS) Sensors are the most popular in the e-nose market owing to their sensitivity, affordability, and rapid onset of response. With these sensors, the molecular interaction with the absorbed gas causes a change in the conductivity of the metal oxide semiconductor target material, which is then detected. Their robustness and compatibility with the embedded system make them ideal for environmental monitoring, food quality assurance, and industrial safety, where aroma detection and data integration need to be undertaken continuously.

Known for its precision and sensitivity to small mass changes, the Quartz Crystal Microbalance (QCM) technology is the one where an increase in mass (volatile compound adsorption onto its surface) is detected by a frequency shift in quartz crystals. The accurate profiling of odors and scent analysis relies heavily on QCM, especially in laboratories, pharmaceuticals, and research applications. Furthermore, Conducting Polymers (CP) exploit organic materials whose electrical properties change upon exposure to certain gases. CP sensors are known for their selectivity and versatility and are being used in portable devices for freshness evaluation, authenticity testing, and point-of-care diagnostics, often using AI-based platforms.

Breakup by End Use Industry

• Military And Defence
• Healthcare
• Food And Beverage
• Waste Management (Environmental Monitoring)
• Others

While explosives, dangerous gases, and chemical threats will be detected with the help of the electronic noses in the military and defense sectors for situational awareness and threat assessment in combat and security operations, the electronic noses together with data catalogs create systems for real-time pattern recognition and fast decision-making using historical sensor data. In healthcare applications, the focus in disease diagnosis is on scent detection for early detection of diseases such as diabetes, cancers, and infections. The electronic nose deals with breath samples and body odors for non-invasive and real-time diagnosis.

For the food and beverage sector, electronic noses are employed for freshness assessment, shelf-life studies, and quality controls. These sensors assure product safety and consistency. Odorus control, air quality monitoring, and harmful emission identification are some of the activities performed by electronic noses under waste management and environmental monitoring.
