Smell sensing system

Abstract

The present application relates to a smell sensing system (100) comprising a smell delivery device (104) for delivering an olfactory output (110). The smell delivery device (104) comprises a delivery channel (3) for receiving a substance (5a) from a canister (5), the substance (5a) configured to produce an olfactory output (114). The smell delivery device (104) also comprises an output component (7) through which the substance (5a) is emitted. The smell delivery device (104) also comprises one or more airflow generating elements (13) configured to generate airflow to transport the substance (5a) from the canister (5) to the output component (7). The smell sensing system (100) also comprises a smell sensing device (102) for detecting the olfactory output (110) delivered by the smell delivery device (104). The smell sensing device (102) comprises at least one gas sensor (31, 32) configured to, in response to the olfactory output (110), generate sensor information (114) corresponding to the olfactory output (110). The smell sensing device (102) is configured to output the sensor information (114) to a processor (106).
