  1. 1. Design and implementation of an energy harvesting system in a prosthetic limb

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ódinn K. Rúnarsson; [2023]
    Nyckelord :Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER

    Sammanfattning : storage devices in micro sizes are receiving more and more attention. One of them, on-paper Microsupercapacitors (MSCs), has become a key energy storage device because of its good mechanical flexibility and high power density. LÄS MER

  5. 4. LactateStat: Wearable Electronics and Software for Real-Time Lactate Monitoring in Sweat

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Emil Ekelund; [2021]
    Nyckelord :Sports Technology; Wearable; Potentiostat; Real-time; Lactate; Sweat; Idrottsteknologi; Bärbar; Potentiostat; Realtidsövervakning; Laktat; Svett;

    Sammanfattning : Lactate is an important biomarker in sports and the lactate threshold concept is one of the best indicators of endurance performance in an athlete. However, to quantify the lactate threshold, an invasive method to take a blood sample must be used. LÄS MER

  7. 5. Flexible and recyclable electronics made from nanoreinforced silk

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Marek Bukovský; [2020]
    Nyckelord :Wearable electronics; flexible electronics; silk fibroin; MXene; nanocomposites; Bärbar elektronik; flexibel elektronik; silkes fibriller; MXene; nanokompositer;

    Sammanfattning : Forskningsområdet för bärbar elektronik är fortfarande relativt ungt och det finns ett stort behov av utveckling av nya material inom området. Olika typer av kompositer är mycket intressanta och de ska uppvisa såväl hög hållfasthet som goda ledande egenskaper. LÄS MER
