The smallest radio

Scientists from Harvard School named after John Paulson created the smallest radio receiver in the world. It consists of blocks of just two atoms in size.

A tiny radio consists of pink diamond particles. It can work even in the most unfavorable environment and is biocompatible with the human body. This means that the radio receiver will work with equal efficiency in the space probe on the surface of Venus and inside the pacemaker in the human heart.

To create the “bricks” that make up the radio, scientists replaced the carbon atom in a tiny diamond crystal with a nitrogen atom and removed the neighboring atom nearest to it. Such a microsystem is capable of emitting single photons or registering extremely weak magnetic fields. Also, it has the properties of photoluminescence – that is, it is capable of converting information into light. This makes it an extremely valuable discovery for the spheres of quantum engineering and photonics .

Radio successfully passed the tests in a variety of conditions. For example, due to the exceptional properties of the diamond, it was able to play music at 350 ° C.
