  4. 3. 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.
