The digital scent technology market is expected to grow from USD 1.0 billion in 2021 to USD 1.5 billion by 2026, at a CAGR of 9.2%. Expanding application and advancements in e-nose technologies,increasing use of e-nose devices for disease diagnostic applications, and emerging R&D activities to invent e-nose to sniff out COVID-19, and rising use of e-nose in food industry for quality assurance in production, storage, and display—are the key factors driving the digital scent technology market.

Based on the hardware device, the digital scent technology market has been divided into e-nose and scent synthesizer. E-nose held the highest share in 2020. E-nose traditionally is used in sectors such as food & beverages and cosmetics for quality control. Now, e-noses are majorly used in medical diagnosis, environmental protection, and explosives detection. Some major companies and research organizations, such as the eNose Company (Netherlands), Le Laboratoire (France), and Scent Sciences Corporation (US), develop e-noses. E-noses are classified on the basis of different sensors. The more commonly used sensors for e-noses include polymer sensors, piezoelectric sensors, MOSFET sensors, and optical fiber sensors.
