Evaluation of magnetoelectric sensor systems for cardiological applications

Thin-film magnetoelectric sensors are able to measure very low magnetic fields. As a consequence the hypothesis that magnetoelectric sensors could be used for biomagnetic measurements was often mentioned but never proven. In this contribution the first proof of this hypothesis will be given by the measurement of the (well-known) R-wave of the human heart. This will be achieved by closing the gap between the sensor sensitivity and the signal...
