We have developed a nine-channel superconducting quantum interference (SQUID) magnetometer system integrated in a 16 mm × 16 mm area. Multi-loop relaxation oscillation SQUIDs (ROSs) are used as magnetometers. Typical field resolution of the ROS is 10 fT Hz−0.5 at the white region. The distance between neighbouring two magnetometers is 4 mm and the magnetometers are as close as 3 mm to subjects. Therefore, it is possible to measure magnetic fields with high spatial resolution and high S/N ratio. Using this system, we measured the magnetic signals due to the action potential propagating along the peripheral nerve of a human.
