Nanocomputers – revolution of technology
Computer implants – for the average person is a term from futuristic literature. It seems as if the world will have to develop to real cyborgs for at least another half a century. In fact, “robotic” people appeared 20 years ago. And the first was the British scientist Kevin Warwick. He was the ancestor of the so-called cyborgs.
In the late 90s, Warwick injected a silicon RFID transmitter under his arm. With the benefit of it, the researcher was able to control the sensors for closing the door, lighting and other equipment. But such results did not satisfy him and he took it a step further – introduced the chip into the nervous system and connected it with his hand. For this reason he got the nickname “Captain Cyborg”. And there are a lot of such stories, in fact.
For a similar example, one can cite a study at the University of Michigan led by David Blaauw, a professor of electrical engineering and computer engineering. So, the researchers used energy-saving processor, Arm corporation, to create the tiniest computer.
The first thing that attracts attention in this device – its size – 0.3 mm. The created equipment still remains the champion in its category, ahead of the previous computer, the size of a grain of salt, ten times. The main application of the chip is temperature and pressure measurement. Thanks to these capabilities, scientists are going to use this sensor in the treatment of cancer. After all, as it is known, they differ from other tissues by a higher temperature.
Problems of nanocomputers
But it’s not that simple. The only obstacle to the spread of such a computer in the field of medicine – battery. Naturally, the larger the size of the battery, the more energy it can store. A chip of 0.3 millimeter does not have much space for a charge. With the reduction in the size of the sensor, they had to sacrifice its energy intensity. According to the scientist, they have reduced the computer along with the batteries a thousand times.
So far, experts proposed three ways to charge such devices. The first – through infrared rays. It is now experimented on laboratory mice. Next – using thermoelectric energy collecting. But it is likely to be a failure. After all, the essence of this method is to create a difference between the two parts of the gadget. But the chip is so small that making one half hotter than the other is almost impossible. And the last option is to use glucose molecules as an energy transmitter.
But the most likely solution until is way of David Blaauw’s team. According to their plan, nanocomputers don’t always have to be on. They will only occasionally wake the chips for calculations, and then return them to sleep mode.
If these scientists succeed, then in the next decade humanity will be able to observe the technical revolution. In which the living being and the device become one. According to scientists, this innovation has a chance to completely change the approach to existence.
