10 interesting miniature gadgets that you can't see.

As the saying goes, good things are often small and unreal, and there are really a lot of tiny gadgets that are much smaller than mobile phones or tablets. In fact, the development trend of the technology industry has always been "smaller" rather than "big", so the current increase in the volume of smartphones seems a little abnormal. Thanks to nanotechnology, some electronic devices that are small enough to be invisible can have a huge impact on our lives and see how small they really are. 1. Print your own miniature battery 3D printing technology is a new trend in the future you can print anything in the home, even a miniature battery. Currently, physicists have successfully used 3D printers to produce lithium batteries 60 microns wide, almost thinner than human hair. These tiny batteries may one day be applied to devices such as smartphones to reduce the size and thickness of the devices. 2. Small "actor" IBM recently released a video called "A Boy and his Atom", known as the current smallest film. The characters in the short film are made up of carbon monoxide molecules, using two scanning tunneling microscopes to shoot at 1 million times times the rate, and if you listen carefully to the background of the video, you can almost hear the sound of a crawling molecule. 3. Miniature MP3 Player The ipod nano is not the world's smallest MP3 player, with only 19 mm wide and 28 grams of thekube on one side. It only has the fingernails size, supports the popular audio format, and the built-in 2GB memory card, the device also has the playback, the volume and so on the key. Thekube is priced at $34 (about 208 RMB) and is available in black, light green, pink, yellow and white. 4. The smallest semiconductor lasers researchers at the University of Texas at Austin, USA, say they developed the world's smallest semiconductor laser transmitter, only 30 nm wide, can be integrated into the computer processor or communication chip to speed up data transmission, may have a more positive impact on future microprocessor performance. 5 100TB of nano-hard disk compared to traditional mechanical hard drives, solid-state drives seem to have a lot of mini, but the future of the hard drive may be too small for you to find. At present, the German center of free Electron laser scientists have successfully developed 4*16 nano-size magnetic storage unit, can achieve 100TB storage capacity. Of course, this technology is still immature, because it needs to be in the 零下200摄氏度 environment to be able to operate stably. 6. Nano-Computer your smartphone processor should be bigger than this nano computer. The microcomputer, developed by a professor at the University of Michigan, is only 1 cubic millimeters wide, equivalent to the size of a needle. The fuselage is built with two processors, a camera and a pressure sensor, as well as a wireless transmitter and antenna, powered by tiny solar cells. It will be used in the medical field to implant ocular intraocular pressure and transmit data in patients with glaucoma. 7. "Bee" robot maybe one day you feel aroundWhen a bee hums, it may be the Mobee bee robot. The Mobee robot, developed by the Harvard Micro-robot Laboratory, has only the size of an insect and has a pair of wings, a long narrow fuselage and a stabilizing device. It is built with microprocessors, sensors, transmitters and antennas, consisting of 18 different materials that can be used for intelligence gathering. 8. Large capacity small capacitance whether television, computer or smartphone, they need dozens of or even hundreds of capacitors to store and release electricity, so the fuselage size is limited. And the Japanese village field production engineers invented the discrete capacitor, even smaller than the tip of the pencil, not only occupy less space, lighter, also consumes less power than previous products, is expected to be officially launched later this year. 9. The smallest computer carving technology, the smallest computer technology developed by the Technion industry, is able to carve a complete U.S. "declaration of Independence" on a 0.04-square-millimeter chip, using 20 nm technology. The world's smallest declaration of independence has been presented to U.S. President Barack Obama this spring. 10. The smallest 3D map if you already feel it's hard to use a map on your smartphone, this is even worse: IBM scientists produced a 3D map with only 11x22 microns, half the size of human hair. On this map, Mount Everest is only 70 nanometers high and is the smallest 3D map in the Guinness Book of Records.
