The actuators are oil-filled plastic bags, similar to those used to make ice cubes.
About half of each bag is coated on either side with a black electrode made of a conductive material.
Buchner explains that "as soon as we apply a voltage to the electrodes,
they are attracted to each other due to static electricity.

And press the fluid out....
So electrostatic actuators!

People "invent" some gadget that is orders of magnitude away from

breathlessly published.

Sound like US F35
and people fall for it and buy it too, (often forced with US gun to head).
