Electronics is the branch of physics and technology that deals with circuits, transistors, microchips, and the behavior and movement of electrons. It handles electric circuits containing active and passive elements and uses underlying techniques. It is an important part of engineering.

Technologies are growing at a very fast rate in the world, and it is important for technology enthusiasts to pace up with the latest changes in the society.

Electronic devices have become an important part of our day-to-day life. It has become difficult for us to do work without using the electronic device.

We live in a generation that uses electronics and technologies where robots and artificial intelligence is capable of doing human work with more ease and efficiency.

Electronics in our daily life are made up of active and passive electric elements and smaller integrated circuits (IC). 

The ICs, transistors, and diodes are made of semiconductor materials, which work when current flows through them.

History of Electronics

The first electronic device was introduced by an American scientist, Sir Joseph Henry, in the year 1835. He invented a remote switch which was controlled by electricity. 

However, the credit of this invention was given to an English inventor Edward Davy in his electric telegraph c. 1835.

Some other Inventions are:

  • Vacuum Diode – It was invented by John Ambrose Fleming.

  • Transistor – It was invented by the combined effort of John Bardeen, Walter Brattain, and William Shockley.

  • IC (Integrated Circuit) – Jack Kilby invented this.

Applications of Electronics in Daily Life

1. Consumer Electronics

Common people are highly benefited by this industry. Consumer electronics are the electric devices meant for everyday use. Consumer electronics are further categorized as:

Office Gadgets like calculators, scanners, personal computers, printers, fax machines, front projectors, etc.

Home appliances such as refrigerators, a/c, washing machine, vacuum cleaner, microwave oven, etc.

Audio and video Systems like headphones, DVD players, VCRs, microphones, colour TVs, loudspeakers, videogame consoles, etc.

Advanced consumer devices like setup box, dishwasher, ATM, PDA(personal digital assistant), smartphones, barcode scanners, POS-terminals, etc.

Storage devices like DVDs, HDD jukebox, mp3 players, memory cards, etc.

2. Industrial Electronics

This industry basically focuses on making real-time automation. 

This includes:

Industrial automation and motion control, motor drive control, machine learning, robotics and mechatronics, power converting technologies, renewable energy applications, photovoltaic systems, power electronics, and biomechanics.

3. Smart Grid Systems

Smart electric systems take information from communication technology and work accordingly based on the desired power consumption. 

It is an application of artificial intelligence, computing, and networked electric system. Smart meters are the best example of a smart grid system.

Features of Smart Grid

  • They are based on two-way communication.

  • They have interactive sensors.

  • They are Self-monitoring and Debugging.

  • Electricity is distributed validly.

4. Industrial Automation and Motion Control

Machines have increased productivity and efficiency, and hence are saving time and cost. Machines are also safe to use in unmanageable works. That's why the delegation of human-automation has become a preferable choice in industries.

5. Image Processing

3D images have been evolved from multiple 2D images. Algorithms are developed to extract 3D information from 2D patterns.

6. Medical Applications

Uses of electronic devices in daily life have seen a major sector in the food industry. Without food, we won't be able to live and survive, as it is necessary for body function. Modern machines produce food in high quantity every day.

Do You Know?

Some capsules and tablets consist of wireless sensors, which are used to collect information from the body of a person. Transparent smartphones are also expected in the coming days. We can see through them. 

There can also be windows and mirrors which can be used a PC screen and monitors. Sensors are imparted in plants to know if they are in a shortage of water.

FAQ (Frequently Asked Questions)

Q1. What is Power Electronics and its applications?

Ans- Power electronics is used to control and convert electric power. It is an application of solid-state electronics. 

The power range is normally in between some ten watts to a few hundred watts. 

Variable speed drive (VSD) is a common application of power electronics in the industry and is used to control an induction motor.

Q2. How is Electronics used in Meteorological and Oceanographic

Ans- Automatic weather stations use electronic sensors to monitor environmental conditions. Some of them are:

  • Barometer: It is a device that measures atmospheric pressure. If the pressure is low, it indicates bad weather like rainfall and storm. If the pressure is low, it indicates good weather conditions.

  • Anemometer: It is a device that is used to measure wind speed and wind direction.

  • Hygrometer: It is a device that is used to measure the humidity in the air.
