Project A7

Electrically Modulated Magnetoelectric Sensors

This project will investigate electric modulation of the magnetoelectric sensors following two approaches:

  • frequency conversion using electric AC fields to shift the low frequency magnetic fields into the mechanical resonance and
  • measurement of static or low frequency magnetic fields while the magnetoelectric sensor is electrically excited in its mechanical resonance.

The work program includes the setup of physical models, the determination of essential parameters for the functional layers in the composite, the design, fabrication and characterization of electric field modulated sensors.

Role within the Collaborative Research Centre

The Collaborative Research Centre 1261 “Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics” spans a wide range of projects: from materials research to sensor concepts to signal processing and finally to applications. Because this project deals with one of the sensor concepts, it is fully integrated within this research chain and we will have intense collaborations with materials research, sensor systems and with signal processing projects. In particular, the following collaborations with other projects are planned.

A1: Collaboration in the investigation of magnetic domain structures (strong collaboration).
A3: Consideration of concepts to increase the quality factor of bending resonators.
A4: Comparison with ΔE-effect sensors.
A6: TEM investigations of magnetostrictive multilayers.
A8: Comparison of modeling and experiments on electrically modulated ME sensors (strong collaboration).
B1: Collaboration noise analysis of electrically modulated ME sensors, and on the physical model for the modulation process (strong collaboration).
B2: Collaboration in the comparison of electrically modulated ME sensors with other approaches within the CRC.
Z1: Collaboration in the MEMS fabrication (strong collaboration).
Z2: Collaboration in the functional characterization (strong collaboration).  

The project will contribute to the focus groups F1 “Modeling” and F2 “Sensor Concepts”.
