In electronics, cryoelectronics or cryolectronics is the study of superconductivity under cryogenic conditions and its applications. It is also described as the operation of power electronic devices at cryogenic temperatures. Practical applications of this field is quite broad, although it is particularly useful in areas where cryogenic environment exists such as superconducting technologies and spacecraft design. It also became a special branch of cryophysics and cryotechnics and plays a role in operations that require high resolution and precision measurements.
