Abstract Some magnetoelectric sensors require predefined external magnetic fields to satisfy optimal operation depending on their resonance frequency. While coils commonly generate this field, a microelectromechanical systems (MEMS) resonator integrated with permanent magnets could be possible replacement. In proof-of-concept study, the interaction of MEMS and ME sensor is investigated compared standard approach achieve best in terms sensitivity. The achievable sensitivity was evaluated...

Magnetoelectric sensor concepts typically require magnetic or electrical excitation signals with a specific frequency and amplitude for operation. These required present challenge in terms of the necessary accuracy to enable ME sensors operation at their particular resonance frequency. This work compares two digital designs generating signal that drives composite sensors. The first one includes Variable-Content Look-Up-Table Single-Side-Band modulation, second is Direct-Digital-Synthesizer...
