In this paper, we describe how magnetoresistive sensors can be integrated with microelectromechanical systems (MEMS) devices enabling the mechanical modulation of DC or low frequency external magnetic fields to high frequencies using MEMS structures incorporating magnetic flux guides. In such a hybrid architecture, lower detectivities are expected when(More)
This work describes how needle shape silicon probes with integrated magnetoresistive sensing elements can be used in neurosciences. The fabricated probes allow simultaneous electric and magnetic recording with a micrometric spatial resolution, therefore offering great advantages for the detection of neural magnetic fields. In this paper we present results(More)
