Research: Biomagnetic Sensing, Sensor Readout and Biomedical Signal Processing

Topic: Magnetoelectric Sensor Characterization

Dedicated research is currently being conducted on novel thin film magnetoelectric (ME) sensor concepts for medical applications. These concepts enable a contactless magnetic signal acquisition in the presence of large interference fields like the earth's magnetic field and are operational at room temperature. As more and more different ME sensor concepts are accessible to medical applications, the need for comparative quality metrics significantly arises.

The objective of this DFG founded CRC project is 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 first week of September, we were delighted to host Dr. Isabel Schiller, an early-career researcher from RWTH Aachen University's Work and Engineering Psychology Lab. Isabel is a Clinical Linguist, holds a PhD in Psychology, and is passionate for auditory cognition and voice research. Together, we've embarked on a collaborative endeavor centered around auditory feedback modulation. Our goal is to develop and assess a real-time voice modification system, designed to explore vocal motor control in both healthy speakers and those with voice disorders. As we joined forces this week, we laid the groundwork for the technical implementation of our project and prepared the upcoming launch of our first experiment at RWTH Aachen University. Interdisciplinary collaborations like this one highlight the importance of merging knowledge from different domains, not only for advancing cutting-edge research but also for fostering an enjoyable and enriching experience.
