Against the backdrop of global industrial quality control undergoing digital transformation, consumer demand for immersive innovation, and the deep integration of sensing and synthesis technologies, olfactory technology products—as intelligent systems enabling the digital perception and reproduction of scents—are pioneering new application domains through their comprehensive closed-loop capability of ‘from scent to reproduction’. Market demand for these products is demonstrating steady growth. According to research by  YH Research , the global revenue for olfactory technology products is projected to reach approximately ¥388 million in 2024, rising to nearly ¥614 million by 2031, with a compound annual growth rate (CAGR) of 6.6% from 2025 to 2031. Its dual value in industrial quality control and consumer experience enhancement not only drives the transformation of traditional odour management models but also establishes a new ‘digital olfaction’ ecosystem, providing technological support for innovative applications across multiple sectors.

Olfactory Technology Products: The “Closed-Loop Core” of the Digital Olfactory Ecosystem

Olfactory technology products constitute a comprehensive intelligent system integrating gas detection, odour recognition, and odour reproduction technologies. Their core objective is to overcome the traditional perception of odours as “invisible and intangible”, enabling the digital capture, analysis, storage, and reproduction of scents. Their core logic involves simulating human olfactory mechanisms: first, precisely identifying and quantitatively analysing gas molecules; then synthesising or releasing specific odours based on analytical data. This establishes a complete closed-loop from ‘odour input’ to ‘odour output’, enabling odour information to be digitally processed and transmitted like sound or images.

From an industrial ecosystem perspective, electronic noses and gas synthesizers form the twin pillars of the digital olfaction industry. Together, they constitute a complete digital odour processing chain: the electronic nose serves as the ‘odour input terminal’, specialising in odour molecule identification and analysis. Through gas-sensitive sensor arrays and pattern recognition algorithms, it converts complex odours into quantifiable digital ‘odour spectra’; The gas synthesiser, as the ‘odour output terminal’, is responsible for digitally reproducing odour information. Based on the digital spectrum output by the electronic nose, it reconstructs target odours by precisely controlling the ratio and release of multiple odour raw materials. This ‘input-output’ closed-loop design liberates olfactory technology products from the limitations of single detection or single release, endowing them with comprehensive digital processing capabilities for the entire odour process.

From a technical perspective, olfactory technology products exhibit three key advantages: high precision, digitalisation, and synergy. High precision manifests in the resolution for identifying odour molecules and the similarity achieved in synthesis, enabling the capture and reproduction of minute, complex odour components. Digitalisation enables the storage, transmission, and editing of odour information, transcending temporal and spatial constraints; Collaboration achieves seamless integration of ‘perception-analysis-synthesis’ through the interplay between electronic noses and gas synthesizers, expanding the technology's application boundaries.

Market Development Trends: Dual-Track Industrial and Consumer Trajectories with Differentiated Application Scenarios

The global olfactory technology market exhibits a distinct dual-track development pattern, with parallel growth in ‘industrial applications’ and ‘consumer experiences’. These two domains, driven by their specific requirements, have formed differentiated application layouts and growth trajectories, collectively propelling market expansion.

The industrial application segment centres on electronic noses, whose objective quantification capabilities create essential demand in quality control scenarios. Within industrial production, odour serves as a critical indicator of product quality and safety. Traditional manual olfactory detection, however, suffers from limitations including strong subjectivity, poor stability, and difficulty in quantification – shortcomings precisely addressed by electronic noses. Their applications are concentrated in food, cosmetics, chemicals, and environmental sectors: in food processing, they provide spoilage alerts and flavour consistency testing, using real-time odour monitoring to assess freshness and production process stability; in cosmetics, they verify raw material purity to prevent substandard ingredients from compromising product quality; in environmental management, they trace malodours to precisely locate industrial emissions or domestic pollution sources, providing data-driven support for environmental remediation. The industrial sector's critical demand for detection accuracy and efficiency positions electronic noses as vital tools for quality control upgrades, driving steady market growth.

On the consumer experience front, gas synthesizers form the core technology, exploring commercialisation pathways through innovative applications. As consumption upgrades, user expectations for experiences extend beyond visual and auditory to multi-sensory immersion. Scent, as a crucial sensory element, becomes key to enriching experiential depth. Applications of gas synthesizers focus on immersive entertainment, new retail, automotive, and healthcare sectors: - In immersive entertainment (VR/AR, 4D cinemas), synchronously releasing scene-matched scents (e.g., woodland aromas for forest settings, gunpowder odours for battlefields) heightens realism; - In new retail, utilised for olfactory marketing by deploying specific fragrances to attract customers and enhance brand recall; In the automotive sector, they enable intelligent fragrance customisation, automatically adjusting cabin scents based on user preferences or driving scenarios; within mental health applications, they assist emotional regulation and psychological therapy by releasing soothing aromas. Though consumer-facing applications remain in an exploratory phase, their substantial growth potential positions them as a new market growth engine.

Industrial Chain Landscape and Technological Trends: Upstream-Downstream Synergy Accelerates Integrated Convergence

The olfactory technology product supply chain exhibits a structure characterised by ‘dual-track upstream supply, closed-loop midstream integration, and downstream scenario differentiation’. Concurrently, a clear trend towards technological convergence is propelling the industry towards integrated ‘perception-analysis-synthesis’ capabilities.

The upstream supply chain exhibits dual-track characteristics based on product type: - Gas synthesizers rely on fine chemical raw materials (e.g., synthetic fragrances, natural essential oils, solvents) and microfluidic core components (e.g., piezoelectric micropumps, nanoscale nozzles, precision control valves). The former determines scent variety and quality, while the latter influences release precision and stability. The upstream of electronic noses centres on the R&D of gas-sensitive materials (e.g., metal oxides, graphene, conductive polymers) and the manufacturing of MEMS sensor wafers. The performance of gas-sensitive materials directly determines the sensitivity and selectivity of sensors, while MEMS processes drive the miniaturisation and cost reduction of electronic noses. Technological breakthroughs in upstream core materials and components form the foundation for enhancing downstream product performance.

Technological convergence is emerging as the industry's central trajectory, with leading institutions actively developing integrated ‘perception-analysis-synthesis’ platforms. These platforms enable electronic noses to capture real-time odour spectra from target environments. Data is transmitted to cloud-based analytics for processing, after which remote gas synthesizers reconstruct the target odour, achieving ‘real-time capture – remote transmission – precise reproduction’. This integrated technology demonstrates disruptive potential in fields such as remote quality control (e.g., multinational corporations conducting remote product odour inspections) and medical diagnostic assistance (e.g., transmitting patient breath odours for disease screening). It holds promise to overcome the temporal and spatial constraints of traditional odour processing, thereby expanding the technology's application boundaries.

The industry currently faces core challenges in standardising odour molecule encoding and ensuring sensor stability: the absence of unified standards for odour molecule encoding hinders data interoperability between devices, constraining large-scale adoption; sensors exhibit insufficient long-term stability in complex environments, compromising detection and synthesis reliability while increasing costs. Future advancements in standardisation frameworks alongside innovations in materials and processes will progressively overcome these challenges, propelling the industry into a phase of scaled development.
