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

We can record smells I’m pretty sure. The issue is with reproducing the smell. You would have to synthesise all the chemicals that result in a particular smell and release them into your nose.
The more likely scenario is we find a way to reproduce a smell by interacting with the brain itself.
It’s a bit like trying to recreate a feeling of touching a specific material e.g. satin. You’d need a piece of satin to recreate it or you somehow activate parts of the brain to recreate that feeling.
