Curriculum Vitae

Fabian Mohn studied Electrical Engineering at the Hamburg University of Technology (TUHH) and in cooperation with the Philips Research Laboratories Hamburg, he received his master's degree in 2018 on the Analysis and Optimization of the Signal-to-Noise Ratio for Receive Arrays in Magnetic Resonance Imaging. He joined the group of Tobias Knopp for Biomedical Imaging at the University Medical Center Hamburg-Eppendorf (UKE) and the Hamburg University of Technology in 2020 as a PhD student and finished his PhD in 2024 on the topic Instrumentation, Sequences and Applications for Magnetic Particles in Imaging and Spectroscopy.

Abstract: A custom-developed magneto-mechanical resonator (MMR) for wireless pressure measurement is investigated for potential applications in process engineering. The MMR sensor utilises changes in the resonance frequency caused by pressure on a flexible 3D printed membrane. The thickness of the printed membrane plays a crucial role in determining the performance and sensitivity of MMRs and can be tailored to meet the requirements of specific applications. The study includes static and dynamic measurements to determine the pressure sensitivity and temporal resolution of the sensor. The results show a minimum sensitivity of and are in agreement with theoretical calculations and measurements. The maximum sensor readout frequency is 2 Hz in this study. Additionally, the temperature dependence of the sensor is investigated, revealing a significant dependence of the resonance frequency on temperature. The developed MMR offers a promising and versatile method for precise pressure measurements in process engineering environments.
