If you do electricity without metal, it makes for cheaper production.
The main problem is you need metal to convert to mechanical force.
But it turns out the electric field also is mechanical, probably weaker, (EDIT: THAN MAGNETIC) but still works. (capacitors.)
So heres a video of it going->

  like rubbing ballons and sticking them to things. Mechanized electrostatic force! There could be a weight reduction potential.

Yes, I think that is the same phenomena,  the positives and negatives attract to each other and the plastic is forced to expand because its being squished together.
Nice eh? =)

[edit] u could make an electrostatic speaker with it,  is that what a piezo electric actually is?!?!?
   
   so its good for maybe a little insect robot?  still has to lift its battery tho...

Might be good for low frequency stuff where mass is an issue because of the low force and capacitance delay. I could see it on a space ship as an hvac component which both circulates and ozonifies the air.

haha Hopefully look at this bobby dazzler-> 
Its towers are tall and dense, and it does seem to be moving its knees pretty easily, but theres something wrong with this picture...
Looks like its from the 1800's just about.

Yes, maybe there are more efficient applications for this technology.
