Do certains smells take you back to a pleasant memory? Soon there could be a way of recording smells to replay over and over again.
"Inventors are on the verge of creating the first mobile ’smellophone’, a gadget which can capture an odour and then replay it back later, just as camcorders do with images.
The invention has been developed by a team at the Tokyo Institute of Technology, led by Pambuk Somboon.
‘In video you just need to record shades of red, green and blue, but humans have 347 olfactory sensors so we need a lot of source chemicals.’ "
