Artificial muscles propel a robotic leg to walk and jump:

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!

Science Daily is such nonsense.

"To date, all the machines they have built -- whether for factories or
elsewhere -- have had one thing in common: they are powered by motors,
a technology that is already 200 years old."

People "invent" some gadget that is orders of magnitude away from
being useful, and press release it as a breakthrough, and it gets
breathlessly published.
