  3. 22. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Författare :Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    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;

    Sammanfattning : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. LÄS MER

  5. 24. Materials and Devices for Stretchable Electronic Nerve Interfaces

    Författare :Samuel Lukas Lienemann; Klas Tybrandt; Magnus Berggren; Diego Ghezzi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Nanowires; Peripheral nerve interfaces; Cuff electrodes;

    Sammanfattning : Within our body, there is a large network of nerves that facilitates communication between the brain and the body’s organs. This network is called our peripheral nervous system, consisting of soft and stretchable nerve bundles that gradually increase in their functional specificity as they split and branch out the closer they get to their target organ.
