Technology makes electronic devices smaller and smaller 10 interesting ultra-small electronic devices
As the saying goes, beautiful things are often tiny and unreal. There are indeed many ultra-small electronic devices that are much smaller than mobile phones or tablets. In fact, the development trend of the technology industry has always been "smaller" rather than "larger", so the current increase in the size of smart phones seems to be abnormal. Thanks to nanotechnology, some electronic devices that are too small to see can have a huge impact on our lives. Let's take a look at how small they are. 1. Print your own mini battery 3D printing technology is a new trend, in the future you can print anything at home, even a micro battery. At present, physicists have successfully used 3D printers to manufacture 60-micron wide lithium batteries, which are almost thinner than human hair. These micro-batteries may one day be applied to devices such as smartphones to reduce the size and thickness of the device. 2. Little "actor" IBM recently released a video called "A Boy And His Atom", known as the smallest movie. The characters in the short film are all composed of carbon monoxide molecules. They were shot at a magnification of 1 million using two scanning tunneling microscopes. If you listen carefully to the background sound of the video, you can almost hear the sound of capturing molecules. 3. Micro MP3 player iPod nano is not the smallest MP3 player in the world, this side is only theKube which is 19mm wide and 28g in weight. It is only the size of a fingernail, supports popular audio formats, and has a built-in 2GB memory card. The device also has buttons for playback and volume. theKube is priced at $ 34 (approximately RMB 208) and is available in black, light green, pink, yellow and white styles. 4. The smallest semiconductor laser Researchers at the University of Texas at Austin claimed that they have developed the world's smallest semiconductor laser emitter, only 30 nanometers wide, which can be integrated into a computer processor or communication chip to speed up data transmission. Microprocessor performance has a more positive impact. 5. 100TB Nano Hard Drive Compared to traditional mechanical hard drives, solid state drives seem to be much smaller, but future hard drives may be too small for you to find. At present, the free electron laser scientists of the German center have successfully developed a magnetic storage unit of 4 * 16 nanometer size, which can achieve a storage capacity of 100TB. Of course, this technology is not yet mature, because it needs to be stable at minus 200 degrees Celsius. 6. Nanocomputer Your smartphone processor should be bigger than this nanocomputer. This microcomputer, developed by a professor at the University of Michigan, is only 1 cubic millimeter wide, which is equivalent to the size of a needle. The fuselage has built-in two processors, a camera, and a pressure sensor. It also has a wireless transmitter and antenna, and is powered by a tiny solar battery pack. It will be used in the medical field to test intraocular pressure and transmit data in the eyes of patients with glaucoma. 7. "Bee" robot Perhaps one day, when you feel that there are bees buzzing around, this Mobee bee robot may be causing trouble. The Mobee robot, developed by the Harvard Micro Robot Laboratory, is only the size of an insect and has a pair of wings, a long and narrow body, and a stabilizer. It has a built-in microprocessor, sensor, transmitter and antenna. It is composed of 18 different materials and can be used for intelligence gathering. 8. Large capacitance and small capacitance Whether it is a TV, a computer or a smartphone, they require dozens or even hundreds of capacitors to store and release electrical energy, so the body size is limited. The discrete capacitors invented by engineers at Murata Manufacturing, Japan, are even smaller than the tip of a pencil. They not only take up less space and are lighter, but also consume less power than previous products. They are expected to be officially launched later this year. 9. Minimal computer cutting technology The smallest computer engraving technology developed by Technion Industries is able to engrave the complete American "Declaration of Independence" on a 0.04 square millimeter chip using 20 nanometer technology. This smallest "declaration of independence" in the world has been given to US President Barack Obama this spring. 10. The smallest 3D map If you already feel that it is difficult to use maps on your smartphone, the following situation will be worse: IBM scientists have made a 3D map that is only 11 × 22 microns, only half the thickness of human hair. On this map, Mount Everest is only 70 nanometers high, making it the smallest 3D map in the Guinness Book of Records. The embarrassment is that with the development of smart phones, big screens are popular. Should n’t the phone get smaller? What do you think?
It is suitable for type 2 diabetes. It is a weekly dipeptidyl peptidase IV (DPP-4) inhibitor. It can control blood sugar levels by selectively and continuously inhibiting DPP-4. DPP-4 is an enzyme that can trigger the inactivation of incretin (glucagon-like peptide-1 (GLP-1) and glucose-dependent insulin-promoting polypeptide (GIP). It plays an important role in regulation. Inhibiting DPP-4 can increase blood glucose level-dependent insulin secretion, thereby controlling blood glucose levels.
