  1. 1. Towards More Efficient Wireless Power Transfer for 6G

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ali Al-Ameri; Jaeyoung Park; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As time is moving forward, the world is becoming more dependent on Internet of Things (IoT) devices. The vision for the future involves IoT devices participating in various aspects of our daily lives, including sensing, controlling, and communicating. LÄS MER

  3. 2. Measurement of mechanical vibrations : Measurement of ambient energy in the form of mechanical vibrations in transportation, storage and installment for the use of self-powered wireless sensor networks

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Oskar Nordström; [2023]
    Nyckelord :;

    Sammanfattning : This project aims to explore the feasibility of using energy harvesting to create a self-powered sensor node that doesn't require batteries. The project was initiated by Ericsson, who identified a need to monitor their radio products during delivery to ensure they are not damaged by vibrations that exceed design specifications. LÄS MER

  4. 3. Coexistence of Dual Inductive Wireless Power Transfer Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Nyckelord :Technology and Engineering;

    Sammanfattning : Wireless power transfer is emerging into everyday life. The idea is to create a more convenient way of charging, or at least powering, devices. LÄS MER

  5. 4. Design of radio frequency energy harvesting system : for use in implantable sensors

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Författare :Amir Ebrahimi; David Kihlberg; [2022]
    Nyckelord :RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

    Sammanfattning : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. LÄS MER

  7. 5. Combining energy harvesting sources for increased system availability and using an input switching algorithm to maximise battery lifetime

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Anton Hylander; [2022]
    Nyckelord :;

    Sammanfattning : Energy harvesting is commonly used for powering low power electronics, for example Low Power Wide Area Networks (LPWAN). Many energy sources are natural (e.g. solar or wind), thus the harvested power can depend on weather, time of day, and time of year. LÄS MER
