Why can’t we record scent

1.03K viewsOtherTechnology

We have invented devices to record what we can see, and devices to record what we can hear.

Why haven’t we invented something to record what we can smell?

How would this work if we did?

\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

When can recreate smells to some degree. 
 
Some expensive candles recreate the smells of certain places such as Indian flower markets or Cathedrals.  

At the other end, scratch’n’sniff stickers recreate simple smells. 

I guess some sort of a portable chromatography machine could be made allowing people to capture a smell at anytime and break it down. It could then be recreated later using a form of printer that combined the required chemicals.
