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

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

    Abstract : 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. READ MORE

  2. 2. Aspects of Electrical Bioimpedance Spectrum Estimation

    Author : Farhad Abtahi; Kaj Lindecrantz; Fernando Seoane; Mart Min; KTH; []

    Abstract : 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. READ MORE

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

    Author : Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; Karolinska Institutet; Karolinska Institutet; []

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
