pure capacitor static actuator driver

thats the transistorless breath through oscillator there! no coils or metal. 100% conductive plastic.
the capacitors are used like diodes.
Cap goes straight to oscillator to remove amps and keep voltage high. OHMS LAW!

Huh?
Electrostatic attraction is nothing new, and nothing to do with diodes or oscillators (or than as part of whatever powers it).

Electrostatic loudspeakers are an example of a practical application.
They are fed with a modulated high voltage and the diaphragm position changes depending on the instantaneous voltage applied, controlled by its attraction to the frame.

This is just an experimental circuit, and that drawing is just an idea about the general concept, its not a diagram to exactly copy.
Its a main storage capacitor that powers it, that gets charged by an electrostatic generator, so its high voltage, then I run an oscillator with it which then runs through some caps into the electrostatic actuator (which isnt pictured.) to turn it on and off and im thinking of making it operate a pneumatic pump, which pumps the leg of the robot. and its fully solid state.


<edit> - made the circuit a bit better.

That picture you showed is how easy it is to make an electric microphone.

Capacitors do not in themselves (or with resistors) oscillate, and caps do not pass steady state DC.
Carefully read my post in your thread on Ohms law.

An "electric microphone" does not mean anything? - all microphones are sound-to-electricity transducers, regardless of the specific technology they use.
If you mean a "Condenser microphone", then they are similar to but simpler than an electrostatic speaker)

eg. This is a condenser mic capsule - the inner disc is on the near side of an insulating membrane with the centre connection & the other electrode is the perforated brass plate, with the spacing set by a thin insulator disc behind the clamp ring.

Micro ohm resistors disturb the current less - but are good at 10/11 circuits.
