One of the projects at the recent Hacker Hotel hacker camp in the Netherlands appeared to have achieved the impossible. A vertical PCB surface was holding pieces of paper as though they were pinned to ...

Hardly a person hasn’t experienced the sudden, sharp discharge of static electricity, especially on a crisp winter’s day. It usually requires a touch, though, the classic example being a spark from ...

Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert electrostatic forces within Earth's crust and potentially contribute to ...

Ordinarily, water is used to clean off the layer of dust that continuously accumulates on solar panels. In arid regions, however, doing so can be challenging. A new system addresses this problem, by ...

There is no doubt that consumers want healthier homes today. An HVAC system air filter upgrade is one way contractors can simultaneously increase customers’ residential IAQ and generate more business.

Many people don’t realize that creating a safe electrostatic discharge workstation can enhance a worker’s productivity and reduce costs associated with damaged equipment. This guide covers all the ...

Electrostatic precipitators (ESPs) have been used for over 100 years to remove entrained solid particulates or fine mists from gas flows in the power, cement, metal production, paper, and other ...

We take a look at the history of the electrostatic loudspeaker and some of the designs that made it prized by audiophiles. Electrostatic loudspeakers have been part of my audiophile experience from ...

The authors have used micromachining techniques to create structures that contain interconnected compartments, each measuring a few hundreds of nanometres in height (Fig. 1). This is advantageous for ...

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. While one ...
