 Now that's an interesting concept. I doubt many of my pots would last long however, the same area being used on it at several thousand times a second. hmmm...I like it though, it's a radical departure of an idea, so it's good for experimenting with!

The strain guage idea is something that seems suitable. The same high gain op-amp method could be possibly used with circuit schematics for strain-guage bathroom electronic scales, or similarly the ones we used to have in the butchers shops in a previous job. Whole thing would be scaled down and ideally respond to breath pressures. Then housed in a shielding that the hair threads through. Ideally, I would think, the hair needs to thread down a clear plastic tube, to remove vocal air pressures in an environment. Any result would then be from the hair and the hair only.
I quite like the idea of procuring well known psychics hair samples for this one, but would have no idea how to approach someone with the request LOL
