    摘要: An electronic device including an olfactory detector including an array of olfactory sensors for determining scents proximate the electronic device, such as a smartphone, smart eyewear, and a smart watch. Each sensor in the array of olfactory sensors is tuned to detect the presence and concentration of one or more specific chemical compounds or molecules. A fan creates airflow of ambient air across the olfactory sensors. An analog to digital (A/D) converter receives and processes the sensor outputs of the olfactory sensors and provides the processed sensor output to a processor for further processing. Scent type and intensity can be classified by using the information from the scent sensors as input for a machine learning model, generated through supervised training using labeled example measurements from our sensor array. The processor may display information of the determined scents on a display of the smart device, and the processor can also send information indicative of the determined scents to another device.
