Is anyone using the TruffleBot electronic nose (or something like it) to detect bed bugs from the VOCs emitted by them?

There's a paper that mentions using VOCs to detect bed bugs:

I think someone tried to do this in 2011, but it didn't seem to take off. A large market exists, so possibly a profitable venture? I don't have the skills or abilities myself.
