I picked some of these Piezo stages up on eBay. They appear to be an OEM design with ~15 microns of travel and I believe a 150v drive voltage. They’re obviously designed for some kind of optics application.

Here’s a video of it in action with the covers removed. The calipers are set at 0.5mm. I’m using a 0 to 150v square wave to drive the Y axis at 4Hz.
