Designer Hee Tae Yang has unveiled a concept model of the artificial nose "Smeller" that smells to determine if food is rotten.

Smeller is a device that can determine whether food is fresh or not more accurately than the nose of the average person. At the tip of the Smeller, an "Electronic Nose" that collects the smell of food is attached, and by bringing that part close to the food and pressing a button, the state of the food is judged.

Smeller determines whether it is safe to eat by comparing the chemical components contained in the odor collected by the electronic nose with the "smell database". The judgment result is displayed on the touch screen in four stages: "Very fresh", "Fresh", "A bit rotten", and "Rotten".

If it is judged to be "slightly damaged", it is recommended to stir-fry and heat it before eating.

The ingredients contained in the scent can be posted on SNS and shared with friends. But don't feel like you don't need this feature.

At this point, unfortunately, Smeller is unlikely to be commercialized.

Creating a database of odors is the key to commercializing Smeller. This is because it is necessary to localize it according to the dietary conditions of each country. For example, if you create a database based on the smell of American food, Japanese "natto" and "kusaya" will probably be judged as "Rotten". It may also be necessary to include the scents of "Durian" for sale in Southeast Asian countries, "Hongeo-hoe" for sale in South Korea, and "Surströmming" for sale in Sweden.

Given the variety of foods in the world, commercializing Smeller certainly seems difficult. However, personally, if I can accurately judge milk and yogurt that have passed the expiration date for several days, I would like to purchase it.
