A student in China has developed a concept device that captures the aroma of a meal on a postcard using a camera, printer and “smell extractor” as part of a Sony design competition.
Li Jingxuan, from the Fashion and Art Design Institute of Donghua University, invented something called a food printer in honour of her love of good food and travel. The idea is that if you are enjoying a trip away you can try local food and then use the machine to take pictures and collect its fragrance. You can then print the picture and smell onto a postcard to send to friends. The system is still a concept at this stage, but would work by using an aroma sensor (or electronic nose).
