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.

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 ...

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.

With the largest tanker fleet in Asia, COSCO Shipping is seeking innovative low-friction hull coatings to meet its greenhouse gas (GHG) emissions reduction targets under the International Maritime ...

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 ...

Guitar notes can be an accurate test of the tonal accuracy and speed of a driver and the CRBN2 proved to be rather adept with both acoustic and electric guitar. Boston’s “Hitch a Ride” features a pick ...

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 ...

The big change though is that the SRM-400S is an all FET design with dual FETs on the first stage and FETs also on the output ...

Normally electrostatic sparks are very small. If the object has a lot of charge, then these sparks can be hundreds of metres long. Sparks can occur between charged objects and people. Sometimes ...

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