In recent years, superconducting quantum interference devices (SQUIDs) based on the Josephson effect have undergone significant advancements. As one of the most sensitive and precise instruments for measuring magnetic fields, SQUIDs are widely used in low-frequency communications, biomagnetic measurements, aerial magnetometry, nondestructive testing, magnetic measurement microscopy, and other fields. The development of SQUIDs involves theories and technologies such as electromagnetic theory, superconductivity, semiconductor technology, thin film fabrication technology, packaging technology, electronic circuits, and cryogenics, reflecting a product of multidisciplinary integration. This paper reviews and summarizes the principles, types, processes, system structures, and current research status of SQUIDs while anticipating future developments in this field.
