Spatial Sensitivity of ECG Electrode Placement
Andra Oltmann, Roman Kusche, Philipp Rostalski
The electrocardiogram (ECG) is a well-known technique used to diagnose cardiac diseases. To acquire the spatial signal characteristics from the thorax, multiple electrodes are comm…
A Robust Multi-Channel EMG System for Lower Back and Abdominal Muscles Training
Roman Kusche, Jan Grasshoff, Andra Oltmann +2
EMG is an established method to acquire the action potentials of contracted muscles. Although commercial EMG systems are available and it is one of the most researched biosignals,…
Multi-Frequency Impedance Myography: The PhaseX Effect
Roman Kusche, Martin Ryschka
Muscle contraction is often detected via EMG in prosthetics. However, signal disturbances due to electrode motions can lead to misinterpretations. Therefore, alternative measuremen…
A FPGA-Based Broadband EIT System for Complex Bioimpedance Measurements -- Design and Performance Estimation
