摘要
Superconducting Quantum Interference Device (SQUID) can provide an ultrahigh magnetic sensitivity for the biomagnetic measurements. In this paper, a SQUID bootstrap circuit (SBC) gradiometer was designed and fabricated. Using the SBC gradiometer, magnetocardiography (MCG), fetal MCG and magnetoencephalography (MEG) signals were detected in a magnetically shielded room.
