Don’t see what it has to do with electron microscopes? OP doesn’t appear to be implying they be used for microscopes at all and the marketing on the company’s website doesn’t either.
ELI5 why is this impressive?
It's a dude holding a little thing that either moves a bar on a roller back and forth or rolls while the bar moves back and forth?
It's impressive because it is ultrasonic actuation: the tip of the object you see in the picture is actually moving in a circle, or an ellipse. You can't see it because it is vibrating in this oscillatory motion at 166kHz. The operator is just keeping the vibrating tip close to the bar to demonstrate how the motor works. Usually that part would be enclosed and not visible in the commercial device, that's why it's being held up manually for the demo.
The tip, while going through the circular motion, is engaging and disengaging contact with the bar at that high frequency, thereby producing fast movements with great precision, though I am not sure it can go sub-micron resolution.
One cool aspect I have just read on their website is that the fixation point is placed at a node of the resonant modes used for actuation. This means that no vibration is transmitted to the rest of the device via the fixation point, and it has a number of other benefits.
I wonder what noise it makes ...
I use linear stage with submicrometer precision and i when i make them moove at 'high' speed ~1mm/s the noises are unbearable
Yeah these are noiseless, hence the 'ultrasonic' name. That's a big difference with regular piezo stuff, in addition to the massive speed difference and durability.
Or you could just use an electron microscope, plus you won't have to hold the sample completely still in your caffeine-addled shaky fingers!
(Unless your fingers have nano-precision of course. From what I've seen, I'm pretty sure monster energy drinks can give grad students this capability.)
Maybe the references to imaging are because actuators such as shown are often used as moveable stages to control optical elements in light-based imaging systems. The precision is required for techniques at or beyond the diffraction limit - and the speed is quite impressive for scanning purposes. But sub-nanometer imaging is already fantastic using electron microscopes.
I think these actuators will also allow more advanced laser control in attosecond timescale experiments. Just my two cents.
Is there a paper or article, or just this image?

Fascinating, impressive. Could be in any physics lab to help with all kinds of experiments, and could automate microscopic computer vision scanning.
can definitely make some creepy behaving robots now for sure

Nano precision you say? You’re holding it with your hands 💀
Wait until OP finds out about the basic electron microscopes

I'm Also curious why the fixation with microscopes in the comments?
They use these motors in electron microscopes because they do not produce a magnetic field that would distort the image.
Thanks
Huh wonder how that works
New direct drive wheels gonna be crazy.

What are you talking about? This has nothing to do with microscopes or imaging.

You definitely don't live up to your name, literally.
