Scientists at Harvard John Paulson School have created the smallest radio receiver in the world. It is made up of blocks only two atoms in size.
The tiny radio is made up of pink diamond particles. It can work even in the most hostile environment and is biocompatible with the human body. This means that a radio receiver will work with equal efficiency in a space probe on the surface of Venus and inside a pacemaker in the human heart.
To create the building blocks of radio, scientists replaced the carbon atom in the tiny diamond crystal with a nitrogen atom and removed the nearest neighboring atom. Such a microsystem is capable of emitting single photons or detecting extremely weak magnetic fields. It also has the properties of photoluminescence - that is, it is able to convert information into light. This makes it an extremely valuable discovery for the fields of quantum engineering and photonics.
The radio has been successfully tested in a wide variety of conditions. For example, due to the exceptional properties of diamond, it was able to play music at 350 ° C.
