Abstract :
Magnetoelectric sensors are assumed to be capable of biomagnetic measurements like magnetoencephalography (MEG) and magnetocardiography (MCG). In this paper a thin film sensor with a ME coefficient of αME = 450 V/cmOe at a resonance frequency of fres = 678.5 Hz is investigated. Measurements show that this sensor reaches a noise level of 7.5 pT/√Hz at resonance and that field strengths in the picotesla range can be detected, which is well in the range of biomagnetic signals.
