The 'super small' world

There are items made by ourselves, but at an extremely sophisticated level that the naked eye cannot see. And even though it's only a few thousandths of a millimeter, they're extremely useful.

We are still not sure how many of these microscopic objects can fill the head of a gout needle (only a few nanometers), but today's advances are so small that scientists can do what they think can not. Here are some "small feats" of experts.

A fly wearing glasses with 2 mm wide eyes.This glasses were created with ultra-precise technology from laser pulses

Ultra-small gear system with 6 gears can help operate micro machines with speeds of up to 25,000 revolutions per minute.Complex electric locks also use these gear systems to be hard to break.Each wheel in the chain will be a key to correctly operating an electrical system.

This gear is created by a focused ion beam.Images are seen under 50,000 times magnification.

This micro-submarine, shaped by using a computer to control a laser beam to "freeze" an acrylic-based liquid, is only 4 mm long.Hopefully, this device will have exciting adventures, especially in medical applications

A 6-micrometer molecular detector (1mm = 1000 mcromet) is made from a platinum bar.This device is used to monitor the distribution of individual molecules while mixing alloys as well as in other materials.Images see below 25,000 magnification.

An array of holes created with a size of about 125 nanometers (1mm = 1,000,000 nanometers) is accurately perforated with focused ion beams controlled by the computer.

The 2mm camel is made of gold leaf and is placed in 300 micrometers wide

A 500-micrometer tick sitting on a mirror system is used for light-ray navigation systems in optical data transmission.This glass (left) is controlled by a micro-gear system.
