The authors have used micromachining techniques to create structures that contain interconnected compartments, each measuring a few hundreds of nanometres in height (Fig. 1). This is advantageous for ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...

If you have an interest in audio there are plenty of opportunities for home construction of hi-fi equipment. You can make yourself an amplifier which will be as good as any available commercially, and ...

Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via ...

The fascinating magnetic properties of the lanthanides have continued to be a highly topical and strongly multi-disciplinary research area for over 60 years. Such is the diversity of this field that ...

The study introduces an atomic single electron transistor that maps the electrostatic potential in a moiré unit cell, ...

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 ...

This study introduces a newly optimized triangular-finger electrostatic comb-drive actuator designed to significantly enhance force intensity and travel range within a compact footprint.

Whether you're a casual gardener or someone who needs to disinfect surfaces frequently for their actual job, you may have encountered the need for a sprayer at some point. In the past, all kinds of ...

Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen and more. New experiments explore how evolution may have influenced this phenomenon.

The original version of this story appeared in Quanta Magazine. Imagine, for a moment, that you’re a honeybee. In many ways, your world is small. Your four delicate wings, each less than a centimeter ...
