Honestly, why not investigate the utility of this? Could one develop a fiber optic coil based microphone? It would probably result in a microphone immune to RF and magnetic interference.

Could that make a mic with no feedback? Might make me replace my SM-58
Besides, if researchers can do this successfully, you would imagine three-letter agencies around the world could do it even better.
You can't just listen to a random fiber on the switch. You'd have to prepare a piece carefully and add the measuring system, by which point a micro is easier and smaller.
Yeah, it basically says, "researchers could potentially measure vibrations in the air to detect speech."
I know. That's how speech works.

And in other news, water makes things wet.
Well, it's more novel than that...
A coil of fiber is not meant to be a listening device, so they almost certainly exist in places where it wasn't previously deemed a risk.
That said, exploiting this in the wild seems like a pretty difficult job, I can't imagine how to do it without already having access to a target computer.
