You might have heard of electrets being used in microphones, but do you know what they are? Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic field.

Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists have found. Caterpillars respond defensively to electric fields similar to those ...

Insects have been known to sense and tap into electric fields, but new research shows that swarms can actually produce atmospheric electric charges. By measuring the extent of this influence, the ...

Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development is one of the 20th century's key scientific milestones. Transistors work ...

At its core, computing relies on manipulating electric currents and fields. But as devices shrink to the nanometer scale, controlling these flows becomes increasingly difficult. Wires and transistors ...
