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 ...

High enough for electrostatic attraction to secure a piece of paper to the PCB. The voltage is generated from an AC source by a Cockroft-Walton multiplier on the back of the PCB, and the front is ...

A study in Engineering reveals a new adsorbent made by combining cationic surfactants with montmorillonite. This adsorbent ...

Insertion loss is typically <0.6dB at 12GHz. IP3 linearity is said to be >95dBm. Contact movement is though electrostatic attraction, with the necessary voltage generated by an integrated charge pump.

This energy overcomes the strong electrostatic forces of attraction which act in all directions between the oppositely charged ions: The strength of the ionic bonds depends on the charge on the ions.
