What? A Radio Receiver from Diamond! But how?
By utilizing the Atomic Level Imperfections of Pink Diamond, the researchers of Harvard School of Engineering & Applied Sciences (SEAS) have developed this Smallest Radio Receiver of the world.
According to the Researchers of SEAS, this Tiny Diamond Radio Receiver functions by utilizing the imperfections also known as N-V (Nitrogen-Vacancy) Centers of Diamonds.
Why is it Incredible? Because the durability which has been explained by its creators is just amazing. From Human body to the planet Venus, anywhere it can be deployed in any tough situation.
One another stunning fact is, this tiny Diamond Radio can play music at a temperature of up to 660 Degrees Fahrenheit and it’s tested. Where the average temperature of Venus is 864 degrees Fahrenheit.
That means it has been played in just 200 degrees lower temperature from the average temperature of Venus.
660 Fahrenheit means approx 348.8 degrees Centigrade. So, it signifies that capacity wise it’s much stronger than any of the average consumer radios.
Check the video shared below to listen music from this tiny radio. One day it could be used to communicate in space as it has already proved its sturdiness.
To create the Imperfections/ N-V centers, researchers had replaced one Carbon atom with a Nitrogen atom and then removed the immediately next Carbon Atom of it.
In this way, the Hole/ Imperfection has been created in the Atomic Lattice of Carbon atoms in diamond.
Now you must be curious to know, how this small creation can house all the elements of a standard radio?
You tell me, with how many elements a typical radio is made of? Mainly with a Receiver, Transducer, Tuner, Speaker & Power Source. Right?
All these 5 elements are also there in this newly invented Diamond Radio but in a bit different way.
Here the power source is a Green Laser light which excites the Electron present in the N-V centers which pick up radio waves.
When the N-V center detects radio waves, the waves get converted into Red light which is directed through a photodiode. Here the photodiode works as the Transducer.
So this transducer then converts the light into electric current. After that using any audio output device (speaker) that electrical current can be converted into audible sound.
In the video shared above, you have already listened the sound coming out of this small Radio.
& you have already identified 4 essential elements of a standard radio, Power Source, Receiver, Transducer & Speaker here. Now, what about Tuner?
When you are listening to music on radio, obviously you will want to change the station. Right? For that, you need a Tuner.
To suffice this need, a magnetic field has been created around the diamond, manipulating which radio frequency can be changed.
Now, what about the quality of the sound? Can it be improved by boosting the signal strength? Yes; Using more N-V Centers the signal can be boosted.
So, better sound quality needs more numbers of imperfections/ N-V Centers.
SEAS Researchers have created an incredible solution by utilizing the atomic imperfections in Diamond.
