The Superconducting Quantum Interference Device, or SQUID, is a sensitive magnetic flux-to-voltage transducer. It may be the most sensitive detector of any physical quantity, with an energy resolution that approaches the quantum limit. The sensitivity of the SQUID has caused it to be incorporated into a variety of systems. SQUIDs have been used to measure cortical activity in the human brain and to search for gravity waves.
