superconducting quantum interference device (SQUID)

SQUID is the abbreviation for Superconducting Quantum Interference

Device. These units are based on quantum interference, which occurs in superconductivity. SQUID is a highly sensitive magnetic field sensor

that can measure magnetic flux densities in the range of quadrillionths of aTesla

(T), equivalent to 10exp-15. Thesensitivity of SQUID sensors is several orders of magnitude higher than that of AMR or GMR sensors

. SQUID sensors are used in medicine to measure brain waves and in magnetic resonance imaging.
