This paper describes multi-channel SQUID systems for biomagnetic measurement developed at KIT and Yokogawa. They are MEG systems, 24-ch systems for peripheral nerve measurement and 9-ch high spatial resolution system. A concept of calibration of the SQUID sensor array is introduced and discussed. Also discussed are noise performance of the system and crosstalk between sensors. Some examples of biomagnetic measurement are introduced using these systems, and their usefulness in the future is discussed.
