"The best way to predict the future is to invent it."

The invention of the transistor started in 1947 at AT&T Bell Laboratories.

Inventors:
William Shockley, John Bardeen  and Walter Brattain.

Early 1960s, the integrated-circuit (IC) was introduced and rapidly became the most powerful semiconductor industry ever in the 21st century. We did it! They did it!

It was predicted that by 2002, billion components will be integrated " onto single-piece of silicon having an area of one-square centimeter (1-Gb DRAM)!" They did it once again. By S. Wolf (microchip manufacturing)

How was it possible by prediction in 2001?


NOTE:
Everyone used electronic devices. People, you, me, love electronics devices simply because we used them everywhere and at all the time.

Examples: Computers, Telephones, Telecommunications-equipment, Cars, Street-Lights are made of integrated circuits which mainly used transistors.

Flash back 1: What is a transistor?

  1. transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit.

Flash back 2: What is electricity?

Electricity is the flow of electron. That 's it! You should know that the electricity that we used every day is a second source of energy. Note that the transformation of the first source of energy such as coal, solar energy and other produce electricity.

Guess what nowOn most modern microprocessors, the majority of transistors are contained in caches. As of 2015 [update], the highest transistor count in a commercially available CPU is over 4.3 billion transistors, in Intel's 15-core Xeon IvyBridge-EX.

circuit board with a 4×4 array of SyNAPSE-developed chips. Built on 28 nm process technology, each chip using 5.4 billion transistors.

What do you think now?

This is just the beginning! 
The evolution of transistors have been such a great success and will remain for long time.

What is Radio waves?


Radio waves: The longest wavelengths with lowest frequency

QWhat it the electromagnetic spectrum?
AThe Electromagnetic spectrum or EM spectrum is the vast range of all different types of electromagnetic radiation. The EM waves have the same vibrations but at a different frequencies.
Here are the graphical representation:




QWhat is the historical discovery?
A:







In 1864, a Scottish theoretical physicist and mathematician James Clerk Maxwell (June 13,1831- November,1879) established the famous equations that bear his name and include the laws of electrostatics and magnetism.

His theory of electromagnetism  is the basis of current designs.
Maxwell's Law of Unification



In 1886, a German Physicist, Heinrich Rudolph Hertz demonstrated the existence of radio waves.

Here are Hertz Equation:
Frequency = (wave speed in m/s) / wavelength λ in m) or  f = λ

Time = 1 / Frequency or = 1 / f

The unit  hertz (Hz) was once called cps = cycle per second

Electricity and Magnetism

Electricity and Magnetism: The importance

          Electricity and Magnetism have been around from the beginning, the beginning of all time.
Electricity and Magnetism are both related. They are everywhere  around us from your telephone, microphone, electric light, automobile, light, radio, computers, planes, planes, train...
Lighting is an electromagnetism phenomenon. The earth itself is rotating around its axis create an electromagnetism.
To be short, they will not be life without an electromagnetism phenomenon.

Q: What is electricity and how it all started?
A:
BEFORE:
Around 600 B.C, ancient Greeks discovered that the amber could attract other objects such as wool when rubbed against each other. This phenomenon demonstrated that materials like amber can be charge and discharge. The word "electric" is derived from the Greek word "elektron", meaning amber

Q: How Electricity and Magnetism are related?

Wireless charging

Wireless Energy: The Next Big Thing


          The concept of wireless energy has been here for a long time. Starting with the pioneer himself, Nicola Tesla. Tesla was an inventor, futurist, physicist, electrical engineer, mechanical engineer, who was best known for the major contributions in developing the modern alternating current(AC) supply system.
This concept becomes the center of research for big companies and independent researchers.
The question is how can we transmit electricity(charging an electronic devices) without using any form of wires? Is wireless Energy a theory or a  futuristic concept? 
Well, let us answer some questions and get deep into the discussion to find out.


Q: What is electricity and how it all started?
A:
BEFORE:
Around 600 B.C, ancient Greeks discovered that the amber could attract other objects such as wool when rubbed against each other. This phenomenon demonstrated that materials like amber can be charge and discharge. The word "electric" is derived from the Greek word "elektron", meaning amber.

Definition:
Electricity is the flow of electron. That 's it! You should know that the electricity that we used every day is a second source of energy. Note that the transformation of the first source of energy such as coal, solar energy and other produce electricity.

By convention, there are two type of charges: a positive charge and negative charge.
case1: two positive charges or two negative charges repel each other.
case2: A positive and  negative charge attract each other. 

See figure below:

Thomas Alva Edison is considered as the greatest electrical engineer of all time. 

He is the father of the DC current which was used by sending electricity over wires and it was the common from of electricity transmission. Cities were power/light up using Direct Current by 1890's.
In 1879, Thomas Edison (1847 - 1931)
invented the first practical long-lasting light bulb(using a small carbonize filament, and vacuum) which used DC(Direct Current) current. 
The world was amazed by his invention, which include some other inventions such, foil phonograph(by 1877), motion picture camera which was tested by 1891.
Edison is considered has the greatest electrical engineer of all time not only by his invention but by its imagination, creativity, ambition, perseverance, determination of building tools that helped the world.

The cylinder phonograph, for example was the first machine that could record and reproduce sound. 
He mentioned that: "I want to see a Phonograph in every American Home." 


During this years, Nikola Tesla (1856 - 1943) a young Serbian-American scientist and ambitious engineer was working for Thomas Edison who was fascinated by another source of energy calls: alternative current or AC electrical system.

Tesla
 believed that one day, the world will be connected by wires using AC.
He is currently considered as the person who develop the concept of alternative current. Some of his invention included, wireless transmission, radio, fluorescent lighting, the Tesla coil transformer and more...

QWhat is AC(alternative current)? and how does it work?
A:
The phenomenon of alternative current shows that electricity which is a flow of electrons in a conductor can periodically reverse their direction of movement. For example, radio station produce alternative current(through waves) which can be tune in low to high frequency.
AC; alternative means (change of direction) and current means (flow of electrons in a conductor).
Tesla believe that electricity could be transmitted through wires at varying current through transformers which he developed.

So, A source of alternative current or voltage is required to produce/supply an alternative current to a circuit. A typical example will be a coil of wire rotating with a constant angular velocity in a magnetic field.
An alternative current varies with time which  produces a waveform or sine wave. There are different types of alternative current waveform.
- Sine wave
- Square wave
- Saw tooth wave
- Triangular wave
- Ram wave

Q: How can we transmit electricity(charging a electronic devices) without using any form of wires? Is wireless Energy a theory or a futuristic concept?
A:
We love electricity and we used electricity everywhere, everyday at an exponential rate.
We need to power our electrical appliance such, TV, Refrigerator, Ipad, phones, DVD player, computers etc... Note that, all these machines have one thing in common: WIRE, yep wire cords. That's sucks, why? Imagine you have to power 10 appliances at once, well you will need a 10 wire wall plug, this is very overwhelming and suck..lol.
Well, we used wireless energy everyday though. Phones, radio, WiFi signals, received and send data or signals ( radio wave).These devices using radio waves communication.
Radio waves transmission is great for transmitted information but not suitable for power transmission.
The major problem of radio waves transmission is that they can become slow when more connection occurs.
The problem of noise and the lower the frequency of the wave, the less it can transmit.

However, how can we tackle this issue of wire cords. Imagine a world without wire, a world where you never have to power you devices with a single wire. This sound too good to be true. lol!
Well, this futuristic concept/idea is now a reality. how?
In 2007, Thanks to a group of theoretical physicists, engineers at MIT(Massachusetts Institute of Technology) invented a new way of transmitting electricity WITHOUT using any form of wire cord. Amazing and exciting! They call it: WiTricity.
They were able to charge a 60 Watts light bulb from a power source located 7 feet(~2 meters) away. This connection was done without any wire between the power source and the device. Nice work huh!
The concept of WiTricity is based on  resonance energy transfer..

Q: What are transformers?
A:
A transformer is an apparatus for increasing or reducing the voltage of an electric power supply to allow device to be connected.

Inside the transformer there are two coils of wire or winding that are close to each other and that actually transmit energy wirelessly through magnetic field in a very short distance. The core of the transformers are made of conducting material such, iron with a very large relative permeability. The constant(relative permeability) keeps the magnetic fields lines concentrated in the core. Note, that for safety reason, magnetic fields are safe to use.

However, MIT researchers team worked on: magnetic couple resonance. They find that, it exists a stronger coupling force between two electromagnetic coupled resonators. The first coil is connected to the power source for energy transmission which energy will be transmit at higher frequency. The second coil( the receiver) resonate with the field(at same frequency as the first) which establishes a connection between the two coils(that will allow transfer of magnetic field). So basically, an ac source causes an alternating current in the sending coil which create an alternative flux within the coils. This will allow a voltage to be induced in each winding or coils. Though, in the receiver coil, the induced voltage create an alternating current in the second winding which then can power any devices connected to it. The MIT team was able to separate this coil from the transformers into a great range distance that will allow them to charge the 60 watts light bulb.

Q: What about safety issues?
A:
The magnetic field do not radiate and stay in close surface within the device or in short distance.
There are very safe for humans to use them. The system only use Magnetic field not Electric field which radiate.


Conclusion:
Note that this transfer of electricity(AC)) can only be done in a short distance.
Nevertheless, we can now say that there is possibility to charge at a very short distance an light bulb. So, in a future, we will be able to have one device that will automatically charged all our electronics devices when they need it. Life will be much easier for me and you probably.
Finally, we can say that wireless energy is not a futuristic concept anymore. Wireless energy is not a imagination but a reality.  I believe one day soon, I would be able to charged all my electronics wiressly, without have to be worry to look for a plug. Perhaps, one day, this system will be efficient to power not only in short distance but in long distance.
From electrical cars, to home appliances, from mobile devices to medical devices, this concept will change the way we use electricity by making it simpler and safer.
