NFPA 70E says, “The electrical safety program shall identify the principles upon which it is based” [110.5(E)]. Someone could read this and then make a list of unhelpful verbiage to satisfy the ...

Electrostatic actuation provides efficient, low-power and fast-response driving and control of movable micro and nano structures, for example, in high frequency switches, oscillators, mirrors, motors ...

ON May 26 Messrs. A. Johnsen and K. Rahbek, two Danish engineers, gave a most interesting demonstration to the Institution of Electrical En gineers of new electrostatic microphones, telegraphic relays ...

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 mechanism is based on a classic electrostatic principle: image charges," Domaretskiy explained. "Our graphite gate works in exactly the same way, but with extreme efficiency because it's so close ...

MEMS mirrors are being used to advance perceptual computing technology, which promotes human-computer interaction through the use of electrostatic principles. While traditional forms of device ...

Static electricity often just seems like an everyday annoyance when a wool sweater crackles as you pull it off, or when a doorknob delivers an unexpected zap. Regardless, the phenomenon is much more ...

The vast majority of motors that we care about all stick to a theme. They rely on the electromagnetic dance between electrons and magnets to create motion. They come in all shapes and sizes and types, ...

This electrostatic oil cleaning system removes insoluble contaminants, including tars and varnishes, from hydraulic oil system. The system uses electrostatic principles to draw contaminants out of the ...
