Wow, this sounds very ambitious!
Perhaps you could somehow attach the piezoelectric component or bars to a micrometer [1] which is designed for accurate and repeatable measurement?

- marcosdumay 5y agoYes, I could. I believe the most straight forward design would be 3 micrometers directly supporting the piezoelectric component, with no levers. Yet, they are a bit expensive. I'm still not willing to budget all that, but I'm starting to consider it.
- minhmeoke 5y agoDigital micrometers are expensive, but you can get analog ones on AliExpress [1] or other places for around $10. Of course, the precision may not be as good as name-brand (eg: Mitutoyo) tools.

- marcosdumay 5y agoYes! Thanks a lot. Looks like the exact thing I need are micrometer heads, and some even come with nice threaded mounts.
- minhmeoke 5y agoExcellent, glad that you found this to be helpful. Good luck with your project!
- minhmeoke 5y agoOne more idea, there exist worm drive micrometers which allow you to step down the linear movement per revolution even more: https://www.global-optosigma.com/en_jp/Catalogs/pno/?from=page&pnoname=WGP&ccode=W8005&dcode= https://www.global-optosigma.com/en_jp/Catalogs/pno/?from=pa... If you have machining/fabrication skills, it might also be possible to buy a few worm gear sets and modify your micrometer to move really slowly but precisely.
