This paper reviews the recent development of mobile nondestructive evaluation (NDE) systems using high-Tc superconducting quantum interference devices (SQUIDs) for conductive materials and structures. The contents of this paper include a noise cancellation scheme using active shielding, a novel high-Tc SQUID gradiometer with robustness in magnetic fields, mobile SQUID NDE systems and NDE of complex composite-metal structures. Using the novel high-Tc SQUID gradiometer, the superior capability of the mobile SQUID NDE system compared to conventional NDE techniques is demonstrated and discussed.
