Abstract

Mixed sensors are very sensitive magnetic field detectors based on the combination of a superconducting loop and magnetoresistive elements, which have already demonstrated their capability to record biomagnetic signals. However, in order to employ these devices in new apparatus, it would be suitable to arrange them in arrays. Here we report the first realization of a mixed sensors array. This is tested with model sources and is then employed to record the magnetocardiographic signal of a healthy volunteer.
