Micro-computers or small computers are devices that have the capacity to enter unknown worlds, including the human body. These computers can change the quality of our lives.
Now, it’s been five years since British scientist Kevin Warwick used the embedded first RFID silicon transmitter in his arm.
Warwick’s goal was to use the transmitter to control computers in the door, lamps, and other gadgets. He then went a step further and connected another device to his nervous system to control a robotic arm. After the invention, Warwick chose the nickname of Captain Cyborg .
While microcomputers are not meet on the headlines every day, their pace of development is still well underway, and there is still some amazing news.
Earlier in the year, for example, a research team at the University of Michigan, led by David Blaw , professor of computer and electrical engineering, made the world’s smallest computer using a low-power processor.
The size of the device is 1.5mm on each side, with only one-tenth the size of the previous model. Since it is possible to build temperature and pressure sensors for these new devices, Blauw’s team intends to avoid the tumors, among other possible applications. To determine what changes in tumor size after chemotherapy or other treatments. This is done by inserting a microcomputer into the tumor.
Although the development of microarrays is exciting, there are obstacles that prevent them from spreading in the health sector. One of the biggest disadvantages of these devices is the production of batteries that can provide enough power. Because as the size of the batteries decreases, the capacity of the energy stored in them decreases dramatically. The batteries required for microcomputers are considerably smaller than conventional batteries, and their capacity will be thousands of times lower.
One possible solution is to use strategies for self-lubrication of microcomputers. For example, infrared rays can remotely charge sensors embedded in the body of rats.
On the other hand,
scientists are researching the matter to supply the electricity needed for microcomputers through the use of thermoelectric energy. However, they have not been able to do so on a small scale yet.
In order to supply thermoelectric power, it is necessary to distinguish between the two parts of the microcomputer. However, the surface of this type of computer is so small that it would be difficult to establish a temperature difference between the two points. There are other methods, such as using glucose molecules to supply energy, which are being investigated.
An effective solution for powering small batteries is to save energy.
Blauw and his team concluded that they could reduce the power consumption of microwaves gradually, allowing the microcomputers to stay active while doing the calculations and then fall asleep.
This solution helps to significantly reduce the power consumption of microcomputers. By improving the transistors, reducing some circuits, and developing some circuit optimizers, Blauw and his team were able to reduce the power consumption of these devices to an extremely small 1 picowatt (equivalent to 300 t / w).
However, if data transfer is not doing properly, downsizing and reducing the power consumption of microcomputers will not matter. Turning on a radio antenna can power the microcomputer in a few billionths of a second without the high cost of energy. Blauw said in his comment:
A loud sound is need to hear the radio. In fact, what we have done is to use long sounds in an instant and short term.
If other research teams, such as the Blau team, can overcome technological barriers,
there will be a dramatic revolution in tumor diagnosis. For example, CubeWorks, one of the accomplishments of the Michigan Microparticles Project, has succeeded in designing a networked microcontroller system capable of connecting to everyday objects.
these microcontrollers can communicate with tools such as home smart systems,
wind farms, blood glucose monitors and other objects connected to the IoT.
These computers can collect information by solar energy such as temperature, ambient pressure, digital images and the direction of movement in an area.
So we can expect the day to come when our interactions with the building we live in
and the clothes we wear change.
Although capacity we are still unable to build submarines in our body,
millimeter computers will enter the market in the next decade and have a major impact on the world.
