really cool stuff. Since the electric charge is flowing the water through the tube i take it no oil vegetable or synthetic will work correct? Feel like this is going to limit the use case down a lot but still maybe big potential in other areas not yet know. Thank you for sharing.
Search for "300% Strain Artificial Muscles" and youll find a video from Stanford that explains it. They use it with pneumatics but the working principle is pretty much the same as using hydraulics like in this video
The power consumption of such EHD pumps is typically quite low. For that reson even "small" power supplies could work but actually youd like the pumps to be way stronger. High voltage isnt easy, yes.. On the bright side you can use smaller gauge wires (lower current). Insulation is very important though. High voltage in general is also more efficient then high current applications because of the lower thermal energy loss. Like with everything there are pros and cons.

Would love to see how an "inverse hydraulic artificial muscle" is built.

Check the Video for IPAM's wich are basically identical but Work with pneumatics rather then hydraulics.
Wait, 6.4kV is not something you can carry in a backpack. How many amps do they take?

Why is there no sound?
Because there are no real moving parts and thus the actuation itself is more or less silent I believe
The moving hydraulic fluid acts as an absorber of vibrations that may arise.
