Electronics Concept, History & What It Is For

What is electronics?

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

For this, electronics use certain basic theoretical principles such as electromagnetism and materials science and other forms of the practical application of scientific knowledge. Its results are of special interest to other fields of specialized knowledge, such as computer science or systems engineering.

Contemporary applications of electronics include:

  • Control systems. They allow us to start or stop processes, as is the case of light circuits in our homes, and can even acquire a certain degree of automation.
  • Power electronics. It is based on the use of electronic devices to regulate electrical power and voltage, especially at significant levels, key in the distribution of energy and other contemporary industrial processes.
  • Telecommunications. It is one of the broadest areas of technological development of electronics that have 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

Electronics started with the so-called “Edison effect.” Thomas Alva Edison in 1883, first noticed thermionic emission, that is, the possibility of releasing electrons from an element by incorporating heat energy into it. This was key in the diode’s invention by Sir John Ambrose Fleming and after the trio 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 the radio, television, and other modern artifacts.

Over time, miniaturization was reached and, therefore, the construction of more practical artifacts with the invention of transistors in the mid-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, cell phones, remote controls, autonomous circuits, etc.

What is electronics for?

Electronics serve a host of 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 its driving mechanisms and materials. Thanks to electronics, we have revolutionized our technological capacity.

Importance of electronics

Electronics Concept
Electronics allow us to build complex implements and autonomous tools.

Electronics is fundamental in the human being’s ability to build complex implements and autonomous tools that allow him to communicate over enormous distances, automate various daily tasks, or make them easier in any case.

The ability to build logical mechanisms that operate from closed circuits of electricity has been essential to spawning a new generation of more powerful and intelligent devices and will undoubtedly offer greater future benefits in robotics and automation.
