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.

The ones in microphones are very small, but in the video after the break [Jay Bowles] from Plasma Channel makes a big electret and demonstrates it’s effects. Electrets have been around since the ...

The purpose of the Center for Integrated Plasma Studies (CIPS) is to provide a focal point and forum for the exchange of both educational and research ideas among plasma scientists at the University ...

Owing to the high electron number density, the electron plasma frequency is extremely high and it far exceeds the electron collision frequency. Such properties lead to many novel effects 4 , 5 , 6 .

An electrostatic loudspeaker uses a thin plastic diaphragm residing between two perforated metal sheets (the grids or stator plates). The audio signal is applied to the grids out of phase.
