  1. 6. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

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

    Författare :Ibrahim Hamed; [2022]
    Nyckelord :Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

    Sammanfattning : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.

  3. 7. Radio Frequency Energy Harvesting In Embankment Dams

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datorteknik

    Författare :William Järvström; Axel Lundberg; [2022]
    Nyckelord :Energy Harvesting; Embankment Dams; Radio Frequency; Wireless Energy Transfer;

    Sammanfattning : Energy harvesting can be used to consume the potential power of the surrounding environment. This harvesting can be done in different ways, some common energy harvesting modalities are vibrations, heat differences, solar power, and RF energy. LÄS MER

  4. 8. Controlling latency for batteryless sensors through environment control

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :David Håkansson; [2022]
    Nyckelord :;

    Sammanfattning : In this study we look at reducing the intermittency of a system harvesting Radio Frequency (RF)signals and/or harvesting photons through a solar cell. This is done through the usage of a smart bulb or a RF generator. Which by increasing the amount of photons or RF signals in the environment, increases the energy in the environment. LÄS MER

  5. 9. Secure Intermittent Computing

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

    Författare :Erik Henricus Wouters; [2019]
    Nyckelord :;

    Sammanfattning : Low-power embedded systems exist in many forms. Using batteries for these devices generally imposes high maintenance costs and there are many applications where a grid connection is not feasible [1]. A solution for powering this class of embedded systems is energy harvesting. LÄS MER

  7. 10. Energy harvesting from ambient WiFi energy : A method of harvesting and measuring ambient WiFi energy

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

    Författare :Alpha Fofana; Carl Mossberg; [2019]
    Nyckelord :Energy harvesting; Rectenna; Impedance matching; Embedded system; IoT; WiFi; Sustainable Energy; Utvinna energi; Impedansmatchning; Inbyggda system; IoT; WiFi; Hållbar utveckling;

    Sammanfattning : The aim of this thesis was to investigate the question of how to harvest RF energy and if we can harvest enough RF energy for it to be useful in an application. It is aimed towards sensor node applications, commonly used in a typical office environment. The WiFi band was chosen since it is omnipresent in the same environment. LÄS MER
