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 ...

What if the very principles that have powered industry for over a century were suddenly turned on their head? For decades, electromagnetic motors—reliant on copper windings and rare earth magnets—have ...

"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 ...

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 ...

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 ...
