  1. 1. On the Feasibility of Using Textile Electrodes for Electrical Bioimpedance Measurements

    Författare :Juan Carlos Marquez; Kaj Lindecrantz; Inkka Vanhala; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; textile electrodes; bioimpedance; Textile Medical Electronics;

    Sammanfattning : The application of textile electrodes has been widely studied for biopotential recordings, especially for monitoring cardiac activity. Commercially available applications, such as the Adistar T-shirt and the Numetrex Cardioshirt, have shown good performance for heart rate monitoring and are available worldwide. LÄS MER

  3. 2. Aspects of Electrical Bioimpedance Spectrum Estimation

    Författare :Farhad Abtahi; Kaj Lindecrantz; Fernando Seoane; Mart Min; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Bioimpedance Spectroscopy; Thoracic Bioimpedance Spectroscopy; Sub-Nyquist Sampling; Undersampling; Aliasing in Electrical Bioimpedance; Bioimpedance Estimation Error.; Medicinsk teknologi; Medical Technology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical bioimpedance spectroscopy (EBIS) has been used to assess the status or composition of various types of tissue, and examples of EBIS include body composition analysis (BCA) and tissue characterisation for skin cancer detection. EBIS is a non-invasive method that has the potential to provide a large amount of information for diagnosis or monitoring purposes, such as the monitoring of pulmonary oedema, i. LÄS MER

  4. 3. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized

    Författare :Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart Rate Variability; Cholinergic Anti-inflammatory Pathway; Autonomic Nervous System; Vagal activity; Biofeedback; Gamification; Serious Gaming; Inflammatory Markers; Raspberry PI; Medical Technology; Medicinsk teknologi;

    Sammanfattning : Heart rate variability (HRV) has received much attention lately. It has been shown that HRV can be used to monitor the autonomic nervous system and to detect autonomic dysfunction, especially vagal dysfunction. Reduced HRV is associated with several diseases and has also been suggested as a predictor of poor outcomes and sudden cardiac death. LÄS MER

  5. 4. Electrical Bioimpedance Cerebral Monitoring : From Hypothesis and Simulation to First Experimental Evidence in Stroke Patients

    Författare :Seyed Reza Atefi; Fernando Seoane; Michael Bodo; Kaj Lindecrantz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Biompedance Spectroscopy; Stroke; Hemorrhage; Ischemia; FEM; HFSS; Electrical Potentials; Människan i vården;

    Sammanfattning : Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. LÄS MER

  7. 5. Model Based Enhancement of Bioimpedance Spectroscopy Analysis : Towards Textile Enabled Applications

    Författare :Rubén Buendía López; Kaj Lindecrantz; Javier Rosell-Ferrer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physiological measurements; Bioimpedance; modelling; textiles;

    Sammanfattning : Several signal processing approaches have been developed to overcome the effect of stray capacitances in Electrical Bioimpedance Spectroscopy (EBIS) measurements. EBIS measurements obtained with textile-enabled instrumentation are more vulnerable to stray capacitances. LÄS MER
