The electrostatic rod can change the motion path of the free-falling raindrop, causing the raindrop to be either attracted or repelled away. These phenomena prove that electrostatic fields are a ...

Normally electrostatic sparks are very small ... like via this conductive rod. There it goes! A spark forms as the electrons jump across the gap. And that’s why you sometimes get a static ...

Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back.
