Aryballe combines biosensors, silicon photonics and machine learning to deliver digital olfaction solutions. Digital olfaction is generally defined as the digital capture and production of aromas. Similar to our sense of smell, it mimics the process by which our brains identify and differentiate between odors.


Odor has such a strong impact on consumer behavior and perception of quality; however, it is also extremely subjective by its very nature—informed by our own personal experiences and preferences.

Human noses provide good information around odor intensity and perception; however, there is wide variation in how a smell is characterized by the human sense of smell—in particular with malodor/unpleasant odors which can illicit strong emotional reactions. It is not the odor itself that is recognized but the odor associated to the emotional reaction.

Mimicking smell

Digital olfaction involves both a sensor—acting as the nose or receptor for odor molecules – and associated software which interprets information from the sensor based on a database of previously collected and analyzed odors. Bio-based digital olfaction technologies mimic the human sense of smell to provide results that align with the human perception.


As objects release odor molecules in response to energy variation or biological processes, these odor molecules are captured by Aryballe’s proprietary biosensors grafted to our silicon photonics-based Core Sensor. This Core Sensor is based on Mach Zehnder Interferometry which produces a unique odor signature (like a fingerprint for odors).

Once the odor signatures are detected, software then interprets those signatures based on a database of previously collected and analyzed odors to provide organizations with actionable insights based on odor data.
