Impact of Structural Design on Magneto-Mechanical Resonators: The Case of a Jewel Bearing Variant
David Conrad, Jan-Philipp Scheel, Frauke H. Niebel +6
Magneto-mechanical resonators (MMRs) are passive, wirelessly read sensors whose small size, miniaturizability, and low cost make them attractive for tracking and for sensing physic…
Parameter Estimation for Model-Based Sensing of Magneto-Mechanical Resonators
Sarah Reiss, Tobias Knopp, Justin Ackers +5
Magneto-mechanical resonators (MMRs) represent a recently proposed type of passive sensor that enables the estimation of its pose as well as sensing other parameters in its environ…
Natural Frequency Dependency of Magneto-Mechanical Resonators on Magnet Distance
Jonas Faltinath, Fabian Mohn, Fynn Foerger +2
The precise derivation of physical quantities like temperature or pressure at arbitrary locations is useful in numerous contexts, e.g. medical procedures or industrial process engi…
Real-Time 3D Magnetic Field Camera for a Spherical Volume
Fynn Foerger, Marija Boberg, Niklas Hackelberg +8
Accurate and efficient volumetric magnetic field measurements are essential for a wide range of applications. Conventional methods are often limited in terms of measurement speed a…
Wireless and passive pressure detection using magneto-mechanical resonances in process engineering
Timo Merbach, Felix Kexel, Jonas Faltinath +4
A custom-developed magneto-mechanical resonator (MMR) for wireless pressure measurement is investigated for potential applications in process engineering. The MMR sensor utilises c…
Low-cost analog signal chain for transmit-receive circuits of passive induction-based resonators
Fabian Mohn, Florian Thieben, Tobias Knopp
Passive wireless sensors are crucial in modern medical and industrial settings to monitor procedures and conditions. We demonstrate a circuit to inductively excite passive resonato…
