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 ...

Most noise-blocking headphones fall into two categories: they use some kind of material to absorb or scatter noise, or they use active cancellation that creates a signal to oppose the noise signal.

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 ...

This e-learning course presents an aid for personnel wanting to increase their knowledge on operation and maintenance of low energy electrostatic ion accelerators and associated infrastructure.The ...

What is Electrostatic Force Microscopy? Electrostatic Force Microscopy (EFM) is a scanning probe microscopy technique that measures the electrostatic interactions between a conductive probe and a ...

Electrostatic precipitators (ESPs) or electrostatic air cleaners are particulate collection devices which use electrostatic forces to separate particulate matter (PM) from exhaust gases. Electrostatic ...

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

With most stand hammocks, they tend to be permanent and immobile. An option like this one is not only foldable, but also ...

At $2,600, the STAX SR-L700 MK2 combo with SRM-D10 MK2 energizer delivers a magical listening experience. STAX has been making electrostatic headphones since 1938 and the Lambda series since 1988.
