Multilayer microhydraulic actuators with speed and force configurations (2021)

Here is a talk by CEO of the company trying to commercialize this technology: https://youtu.be/wPNTPmAIqf4

Wow, thanks for finding this!

I barely understand it, but it looks very interesting!

It's a small (mm2 scale,) high precision, high efficiency stepper motor, fabricated as both rotary and linear devices.

Looks like a big deal to me with many potential applications. A lot of optics applications come to mind, although they're pitching semiconductor manufacturing. The submission link provides several videos (wmv format, for some reason.)

Wow, so what's the mechanism here? It seems like layered or nested stepper motors, with the magnets and coils replaced by liquid surface tension and electrostatic impulse to move droplet from one electrode to another?
