Most of the breakthroughs scientists are producing on the micro scale are consistently both fascinating and freaky.

Airborne microbots, for example, will “float on the wind” in order [allegedly] to study climate changes and the spread of disease.

Now, in another big micro scale breakthrough [called "metasurface," which uses AI or artificial intelligence], a team of researchers from Princeton University and the University of Washington have developed a camera the size of a coarse grain of salt.

All we can think about is how this thing would be perfect as an eye for bug-bots.

New Atlas reported on the salt grain-sized camera, which iterates on previous, micro scale cameras. The researchers note in their paper, published in the journal Nature Communications, that “ultra-small imagers” already in existence have the small-size factor down, but not the image quality. More
