2. 1. Smartware electrodes for ECG measurements : Design, evaluation and signal processing

   Author : Linda Rattfält; Per Ask; Fredrik Björefors; Kaj Lindecrantz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The aim of this thesis work has been to study textile and screen printed smartware electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to movement induced noise by using signal processing. Smartware electrodes for ECG measurements have previously been used in various applications but basic electrical electrode properties have not sufficiently been looked into. READ MORE

4. 2. Textile electrodes for ECG measurements in distributed care, performance and applications

   Author : Linda Rattfält; Per Ask; Peter Hult; Maria Lindén; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The aim of this thesis work has been to explore textile electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to noise with signal processing techniques. Previous research within the field has shown that acquisition of ECG is possible with textile electrodes, but little attention has been focused on how they function and especially if movements are included in the measurement protocol.

5. 3. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research

   Author : Björn Hammarberg; Dick Stegeman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; matched filter; asynchronous detection; Kalman filter; initialization; MHT; Wiener deconvolution; line source model; electromyography; needle EMG; motor unit potential; MUAP; mean fiber concentration; jitter; microneurography; C-fiber; spike sorting; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

   Abstract : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. READ MORE
