Artificial Intelligence (AI) and the Internet of Things (IoT) are significantly expanding the applications of digital scent technology, leading to more immersive, personalized, and functional sensory experiences across various sectors within the B2B market. These technologies can aid in enabling food and beverage, cosmetics, and automotive businesses to make better decisions regarding research and development, quality control, manufacturing, and end-user experiences.

Artificial Intelligence (AI) in Digital Scent Applications:

• Enhanced Sensory Processing and Creation
  • AI-driven sensory technology processes inputs like smell to convert them into valuable information.
  • In entertainment, AI is used by scent-based technologies to create smells based on what the user is seeing or experiencing, blurring the boundaries between physical and digital realms.
  • AI helps to personalize scent experiences, predict optimal scents for different environments, and improve the blending of odor molecules to create more accurate and pleasant scents. A 2023 study even showed a machine-learning model was better at odor recognition for 53% of tested scent molecules, indicating that computers have learned to recognize odors better than humans in some contexts. AI models can predict what molecules ought to smell like just by analyzing their molecular structure.
• Advanced Diagnostics and Health Monitoring
  • AI-enabled “odor surveillance systems” are being developed to diagnose diseases and maintain health. For example, companies like NoZe screen for medical conditions such as tuberculosis using digital smell detection.
  • Companies are developing AI smell detectors that can identify the presence of illnesses, food adulterants, and other potentially harmful chemicals. Alex Wiltschko, CEO of AI olfactory startup Osmo, envisions a future where digitizing smell aids in early disease detection, rapid pandemic tracking, increased food production, early spoilage detection, and pest control.
• Improved Food and Product Testing
  • AI-driven “electronic tongues” are used to streamline flavor analysis and simplify food and drug testing processes. These can analyze different organic and inorganic compounds that impact taste.
  • Electronic tongues can rank product samples based on the intensity of flavors like saltiness or bitterness. They have been designed to analyze water quality by detecting minerals and heavy metals and to test the bitterness of medication to improve treatment adherence, potentially expediting drug development.
  • Advancements in olfactory technology enable computers to detect odors, improving bomb detection capabilities.

Internet of Things (IoT) in Digital Scent Applications:

• Connected and Personalized Experiences
  • The integration of digital scent technology with IoT is creating exciting possibilities for more connected and personalized scent experiences.
  • Companies like Inhalio are developing IoT scent diffusers that can synchronize with other smart home devices to create multi-sensory experiences. For example, a “relaxation” mode could simultaneously adjust lighting, play soothing music, and diffuse a calming scent. In terms of wellness in the workplace, different areas of the office can be tweaked for purposes.
• Remote Management and Automation
  • IoT connectivity allows for real-time monitoring and control of scent devices remotely. Users can adjust intensity, schedule scent releases, and receive notifications when fragrance cartridges need replacement.
  • Devices can learn user preferences over time to create personalized scent profiles, automatically adjusting to preferred scents based on the time of day or activities.
  • Some advanced IoT scent devices can even detect environmental factors like humidity and temperature to optimize scent diffusion, ensuring a consistent and pleasant experience.

Leading brands in integrating scent technology with IoT include Inhalio, known for its Digital Scent AI Platform; ScentBridge, specializing in intelligent fragrance solutions with patented IoT technology; and Aryballe, with digital olfaction solutions that include smart sensors for scent detection and analysis. These advancements, combined with the trend toward miniaturization and portability, are making digital scent technology more versatile and accessible for today’s market.
