1. 1. 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

3. 2. Improvements in Bioimpedance SpectroscopyData Analysis : Artefact Correction, ColeParameters, and Body Fluid Estimation

   Författare :Ruben Buendia; Fernando Seoane; Hermann Scharfetter; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioimpedance; Cole; Body Fluid;

   Sammanfattning : The estimation of body fluids is a useful and common practice in the status assessment of diseasemechanisms and treatments. Electrical bioimpedance spectroscopy (EBIS) methods are non-invasive,inexpensive, and efficient alternatives for the estimation of body fluids. However, these methods areindirect, and their robustness and validity are unclear. LÄS MER

4. 3. Electrical bioimpedance cerebral monitoring

   Författare :Fernando Seoane Martínez; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomedicin; bioteknik; non-invasive monitoring; electrical bioimpedance; spectroscopy; biomedical instrumentation;

   Sammanfattning : Neurologically related injuries cause a similar number of deaths as cancer, and brain damage is the second commonest cause of death in the world and probably the leading cause of permanent disability. The devastating effects of most cases of brain damage could be avoided if it were detected and medical treatment initiated in time. LÄS MER

5. 4. 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

7. 5. Textile-enabled Bioimpedance Instrumentation for Personalised Health Monitoring Applications

   Författare :Javier Ferreira Gonzalez; Kaj Lindecrantz; Fernando Seoane; Javier Jiménez Leube; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; personal healthcare systems; bioimpedance; wearable; portable; monitoring; textrodes; body composition; chronic kidney disease; ambient assisting living; wireless sensor;

   Sammanfattning : A growing number of factors, including the costs, technological advancements, an ageing population, and medical errors are leading industrialised countries to invest in research on alternative solutions to improving their health care systems and increasing patients’ life quality. Personal Health System (PHS) solutions envision the use of information and communication technologies that enable a paradigm shift from the traditional hospital-centred healthcare delivery model toward a preventive and person-centred approach.
