Electrostatic loudspeakers work by the attraction and repulsion of a thin conductive film in an electric field rather than the magnetic attraction and repulsion you’ll find in a moving-coil ...

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 description by Van Wyk and Kühn 1 of their corona motor reminded me that a number of years ago I made an electrostatic motor, in basic concept not unlike their motor, but fitted with metal ...

Magnetic force can overcome gravity. That’s why this magnet can hover in mid-air. Electrostatic force also attracts and repels objects. Rubbing the balloon on another surface creates a small ...

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.

A plotter that uses an electrostatic method of printing. Liquid toner models use a positively charged toner that is attracted to paper which is negatively charged by passing by a line of ...

This transparent "tape," known as an electrostatic sticker, is becoming more common in dashcam kits. Manufacturers aim to ...

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...
