Scientists have learned to transmit smells on the Internet. Researchers from the USA and China have created an "electronic nose". It uses artificial intelligence to analyze the smell and transmit it to the intercom device, which reproduces the smell. The system was tested for smells of coffee, beer, red wine, orange and cake. In most cases, people correctly identified the aroma emitted by the device. However, according to scientists, it is necessary to improve the technology, so they will continue testing. All that remains is to learn how to print food on a printer.
