Towards an Earpiece for Wearable and Dry Ultrasonic Vagus Nerve Stimulation
Sebastian Frey, Farouk Ghezraoui, Marc Nölke +3
Ultrasound (US)-based auricular vagus nerve stimulation (aVNS) is emerging as a versatile, noninvasive modality for neuromodulation - spanning clinical therapies (e.g., pain manage…
U-Sonic: An Open-Source 8-Channel Ultrasound Transmit IP in a 130 nm RISC-V SoC
Federico Villani, Nico Canzani, Marc-André Wessner +5
Miniaturized ultrasound (US) probes require programmable and synchronized transmit (TX) excitation across multiple elements, while existing compact platforms often rely on limited…
MuyBridge: Mobile Human Center-of-Mass Estimation from Monocular Video via Sparse Fusion
Aidan Bradshaw, Marco Giordano, David Rode +8
The 3D center of mass (CoM) is a primary quantity in the biomechanical analysis of sport, rehabilitation, and clinical movement, yet existing 3D pose tracking, mesh recovery, and m…
Multi-Sensor Edge Angle Detection for Performance Analysis in Ski Jumping
Ivan Simeonov, Lukas Schulthess, Hanna Mueller +4
In ski jumping, performance during the gliding phase depends on achieving an aerodynamic posture that maximizes the lift-to-drag ratio. In the V-style technique, the ski edge angle…
A Time-Synchronized Video Reference System for Data Analysis of Body-Attached Sensor Nodes in Outdoor Scenarios
Lukas Schulthess, Fabian Pleisch, Matheo Käch +4
Wearable body-attached multi-sensor systems enable detailed analysis of human motion and physiological signals in sports, rehabilitation, and movement research. While wireless sync…
Wireless Low-Latency Synchronization for Body-Worn Multi-Node Systems in Sports
Nico Krull, Lukas Schulthess, Michele Magno +2
Biomechanical data acquisition in sports demands sub-millisecond synchronization across distributed body-worn sensor nodes. This study evaluates and characterizes the Enhanced Shoc…
PEtra: A Flexible and Open-Source PE Loop Tracer for Polymer Thin-Film Transducers
Marc-Andre Wessner, Federico Villani, Sofia Papa +5
Accurate characterization of ferroelectric properties in polymer piezoelectrics is critical for optimizing the performance of flexible and wearable ultrasound transducers, such as…
PuLsE: Accurate and Robust Ultrasound-based Continuous Heart-Rate Monitoring on a Wrist-Worn IoT Device
Marco Giordano, Christoph Leitner, Christian Vogt +2
This work explores the feasibility of employing ultrasound (US) US technology in a wrist-worn IoT device for low-power, high-fidelity heart-rate (HR) extraction. US offers deep tis…
Towards a Novel Ultrasound System Based on Low-Frequency Feature Extraction From a Fully-Printed Flexible Transducer
Marco Giordano, Kirill Keller, Francesco Greco +3
Ultrasound is a key technology in healthcare, and it is being explored for non-invasive, wearable, continuous monitoring of vital signs. However, its widespread adoption in this sc…
Skilog: A Smart Sensor System for Performance Analysis and Biofeedback in Ski Jumping
Lukas Schulthess, Thorir Mar Ingolfsson, Marc Nölke +3
In ski jumping, low repetition rates of jumps limit the effectiveness of training. Thus, increasing learning rate within every single jump is key to success. A critical element of…
A Wearable Ultra-Low-Power sEMG-Triggered Ultrasound System for Long-Term Muscle Activity Monitoring
Sebastian Frey, Victor Kartsch, Christoph Leitner +4
Surface electromyography (sEMG) is a well-established approach to monitor muscular activity on wearable and resource-constrained devices. However, when measuring deeper muscles, it…
Enabling Failure Recovery for On-The-Move Mobile Manipulation
Ben Burgess-Limerick, Chris Lehnert Jurgen Leitner, Peter Corke
We present a robot base placement and control method that enables a mobile manipulator to gracefully recover from manipulation failures while performing tasks on-the-move. A mobile…
A Human-Centered Machine-Learning Approach for Muscle-Tendon Junction Tracking in Ultrasound Images
Christoph Leitner, Robert Jarolim, Bernhard Englmair +9
Biomechanical and clinical gait research observes muscles and tendons in limbs to study their functions and behaviour. Therefore, movements of distinct anatomical landmarks, such a…
Automatic Tracking of the Muscle Tendon Junction in Healthy and Impaired Subjects using Deep Learning
Christoph Leitner, Robert Jarolim, Andreas Konrad +4
Recording muscle tendon junction displacements during movement, allows separate investigation of the muscle and tendon behaviour, respectively. In order to provide a fully-automati…
Ultrasound in Locomotion Research -- The Quest for Wider Views
Christoph Leitner, Christian Baumgartner, Christian Peham +1
In a systematic review, we investigate current applications of ultrasound in locomotion research. Shortcomings in the range of view of ultrasound systems affect the direct validati…
