An unstructured finite-volume Helmholtz method with perfectly matched layers for heterogeneous two-phase acoustics
Chuanchao Xu, Jun Liu, Jan Helge Dörsam +4
This paper presents a cell-centred unstructured finite-volume method for time-harmonic two-phase acoustics. A volume-fraction representation supplies density and acoustic compressi…
Non-intrusive MEMS microphone sensing of acoustic field state in resonant acoustic levitators
Jan H. Dörsam, Maximilian L. Amberg, Sven Suppelt +6
Reliable operation of resonant acoustic levitators requires knowledge of the acoustic field state because the optimum transducer-reflector distance and resonant operating condition…
Evaluating Acoustic Data Transmission Schemes for Ad-Hoc Communication Between Nearby Smart Devices
Florentin Putz, Philipp Fortmann, Jan Frank +3
Acoustic data transmission offers a compelling alternative to Bluetooth and NFC by leveraging the ubiquitous speakers and microphones in smartphones and IoT devices. However, most…
An Optical Measurement System for Open-Source Tracking of Jaw Motions
Paul-Otto Müller, Sven Suppelt, Mario Kupnik +1
Precise tracking of the jaw kinematics is crucial for diagnosing various musculoskeletal and neuromuscular diseases affecting the masticatory system and for advancing rehabilitativ…
Sensor Insoles: A Review
Bastian Latsch, Felix Herbst, Mark Suppelt +6
Plantar pressure measurement, or pedobarography, is an essential tool for analyzing human motion in healthy individuals and patients. Across the reviewed literature, sensor insoles…
A tensor model for the calibration of air-coupled ultrasonic sensor arrays in 3D imaging
Raphael Müller, Gianni Allevato, Matthias Rutsch +4
Arrays of ultrasonic sensors are capable of 3D imaging in air and an affordable supplement to other sensing modalities, such as radar, lidar, and camera, i.e. in heterogeneous sens…
Magneto-active composites with locally tailored stiffness produced by laser powder bed fusion
Kilian Schäfer, Matthias Lutzi, Muhammad Bilal Khan +11
Additive manufacturing technologies enable the production of complex and bioinspired shapes using magneto-responsive materials, which find diverse applications in soft robotics. Pa…
Acousto-Optic Modulation in Ambient Air
Yannick Schrödel, Claas Hartmann, Tino Lang +15
Control over intensity, shape, direction, and phase of coherent light is essential in numerous fields, reaching from gravitational wave astronomy over quantum metrology and ultrafa…
Frequency-dependent Ultrasonic Stimulation of PNIPAM Microgels in Water
Atieh Razavi, Matthias Rutsch, Sonja Wismath +3
As a novel stimulus, we used high-frequency ultrasonic waves to provide the required energy for breaking hydrogen bonds between Poly(N-isopropylacrylamide) (PNIPAM) and water molec…
