World's Smallest

Researchers at Leiden University in the Netherlands have created the world’s smallest boat. Measuring just 30 microns long, the tiny model was 3D printed as part of a project investigating how to make synthetic “microswimmers” in complex shapes.

Scientists have developed what they claim is the smallest particle sensor in the world, designed specifically to detect harmful pollutants and offer a highly localized picture of air quality by being integrated into wearables and mobile devices.

Some of the most useful tools are the ones that allow you to grab something. However, what if that "something" is very, very small? Well, that's where a new light-activated micro-gripper could come in – it's said to be the world's smallest.

Although we've previously heard about various groups' tiny "microbots," a new one is actually claimed to be the world's smallest microelectronic robot. What's more, it moves by shooting out dual jets of bubbles.

New Atlas tries out the Zanco tiny t2 – the world's smallest working 3G phone – which is designed as a portable secondary device to your expensive smartphone. And yes, it’s exactly as practical as we expected, with a price tag a little too high.

Although tiny houses are becoming increasingly popular, many people wonder if they could ever actually live in one. Well, those folks would be particularly challenged by a new gingerbread-style house, as it’s smaller than the width of a human hair.

In a perfect world, the only objects that anyone would ever wish to print on would be sheets of paper. Given that this isn't a perfect world, though, The God Things has created what it claims is the smallest-ever mobile color printer – the PrinCube.

If you're going to be using a "smart" eyewear device for long periods of time, then it had better be light and unobtrusive. Well, ThirdEye's X2 Glasses may fit the bill, as they're said to be the world's smallest mixed reality glasses.

OmniVision has announced that its OV6948 unit has been declared the world's smallest commercially available image sensor by Guinness World Records. And the company has now squeezed it into a new camera module.

Researchers at Cambridge University have managed to create the smallest pixels in the world, about a million times tinier than those in a phone. These new pixels could be used in huge, flexible displays that are relatively easy to manufacture and cheaper to run.

​Ordinarily, cycling power meters are mounted on the crank, pedal, or sometimes even the rider's shoe. The AroFly, however, takes a different approach – it threads onto the rear tire's Schrader or Presta valve stem. It's also claimed to be the world's smallest power meter.

"World’s smallest computer” is a contentious title, not just because scientists are racing to shrink devices, but because the very definition of a computer could be up for debate. The latest claim to the title is a tiny device that communicates through light and makes a grain of rice look gigantic.
