Magnetoelectric Sensor Characterization
The essential goals of this project are functional characterization of the various ME sensors of the CRC (determination of the spectral distribution of the noise, the limit of detection, the cross sensitivity, and the directional characterization of the ME sensors), manufacturing of the measurement hardware, automation of measurement procedures, and measurement support for the biomedical applications in the corresponding B projects. To give quick access to the impact of material or design variations on ME sensor performance, a database and the corresponding interfaces to the measurement and characterization system as well as to the users (most of the A and B projects) will be established.
Results
Head Scanner Has Reached the Next Level
| The head scanner has been improved with respect to scanning speed, robustness, and saftety means. It is ready now to be used for patient measurements. First evaluations have been performed in close cooperation with the medical project B5. |

A New Head Phantom for Investigation of Connected Soures in the Brain
 |
Furthermore, a head phantom for emulation of a network of connected sources in the brain has been designed in close cooperation with the rearchers from project B3. Small coils can be arbitrarily placed at designated postions. This allows us to generate a variety of source configurations and we are able now to create the corresponding magentic fields on the surface of our artifical head. |
