The smallest in the world radio was created from the defective diamond
A group of scientists from the Harvard school of engineering and applied Sciences (SEAS) have managed to create the world’s smallest radio in pink diamond, according to Motherboard.
It works due to the special defect of the NV-center, or nitrogen-substituted vacancies formed in the crystal lattice of diamond where one of the carbon atoms is replaced with nitrogen.
Mini radio has all the main elements that has classic: power supply, receiver, transmitter of electromagnetic waves into electric current, the tuner and speaker.
Experts say that their device is incredibly durable and capable of operating in harsh environments.
So, the smallest radio can play music at a temperature over 350 degrees.
The researchers plan to continue the study of other defects in diamond for interaction with radio waves.
