Electronics - Term Overview

Home | Blog | Electronics - Term Overview

Electronics is called a technical and scientific discipline, considered as a branch of physics and as a specialization of engineering, which is dedicated to the study and production of physical systems based on the conduction and control of a flow of electrons or of electrically charged particles.

For this, electronics makes use not only of certain basic theoretical principles such as electromagnetism, but also of materials science and other forms of practical application of scientific knowledge. Its results are of special interest for other fields of specialized knowledge, such as computer science or systems engineering.

Contemporary applications of electronics include:

- Control systems: They make it possible to start or stop processes, such as the light circuits in our homes, and they can even acquire a certain degree of automation.
- Power electronics: It's based on the use of electronic devices to regulate electrical power and voltage, specially at significant levels, which is key in energy distribution and in other contemporary industrial processes.
- Telecommunications: It's one of the broadest areas of the technological development of electronics has to do with databases and digital information systems, such as the Internet. As well as with the universe of gadgets or electronic devices available for the so-called 2.0 culture.

History of electronics

Electronics had its beginning with the so-called "Edison effect. " Thomas Alva Edison in 1883 noticed for the first time the thermionic emission, that is, the possibility of releasing electrons from an element from the incorporation of heat energy into it. This was key to the invention of the diode by Sir John Ambrose Fleming and then to the triode in 1906 by Lee De Forest.

The latter is considered the father of electronics, since thanks to his contributions it was possible to overcome the stage in which only power supplies were built, and begin to amplify signals of all kinds, allowing the first steps towards the invention of radio., television and other modern gadgets.

Over time, miniaturization was reached and, therefore, the construction of more practical devices with the invention of transistors in the middle of the 20th century, with which vacuum valves were replaced, saving energy and money.

Already in 1958 the first integrated circuit in silicon plates was developed, housing six transistors on the same chip. From there to the creation of the first microprocessor in 1970 there was a direct journey. Thanks to the electronic industry field and the life of the revolutionized human being at all levels: cell phones, remote controls, autonomous circuits, etc.

What is electronics for?

Electronics are used for countless applications in the contemporary world. Practically all the implements that we use daily ( computers, calculators, cell phones, digital clocks, electrical circuits, remote controls, televisions, radios) have their origin in the development of electronics, in the improvement of their driving mechanisms and their materials.. Thanks to electronics we have revolutionized our technological capacity.

Importance of electronics

Electronics is essential in the ability of human beings to build complex implements and autonomous tools that allow them to communicate over enormous distances, automate various tasks of their daily life or make them easier for them in any case.

The ability to build logic mechanisms that work from closed circuits of electricity has been fundamental to engender a new generation of more powerful and intelligent devices and, without a doubt, will offer greater advantages in the future in the field of robotics and automation.
