  1. 1. Energy harvesting för sensorer i tung industriell miljö

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Elias Tångås; [2023]
    Nyckelord :;

    Sammanfattning : Energy harvesting essentially involves extracting energy from processes that generate losses in theform of heat, vibrations, radiation, etc, and converting it into electrical energy that can be used topower sensors or other electrical systems. A customer of Knightec Örnsköldsvik wants to develop measurement equipment using sensors in a demanding industrial environment with rotating machines that does not allow wired energy or communication transfer.

  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. Energy Neutral User Equipment : powering cellular IoT applications using energy harvesting

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

    Författare :Tomas Lorenzo Henriques Vazquez; [2022]

    Sammanfattning : With the rise in the number of Internet of Things (IoT) applications, there is also an increase in the number of batteries being used to power these connected devices. The lifespan of IoT devices is usually limited by how long their batteries last. LÄS MER

  5. 4. Design of current transformer energy harvesting power supply

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Oscar Bäckman; [2021]
    Nyckelord :Energy harvesting; Current transformer;

    Sammanfattning : This thesis explores the possible method to harvest energy from ambient sources around power transformers. These include magnetic induction and vibration. The objective is to create an energy harvester device that can output enough energy to power multiple sensors, wireless connectivity and an MCU. LÄS MER

  7. 5. Evaluating the performance of a vibration energy harvester under complex excitation

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Zhiqiang Chen; [2020]
    Nyckelord :Vibration energy harvesting; harvester; closed-loop control; resonant frequency; prediction;

    Sammanfattning : In recent years, vibration energy harvesting has become a research hotspot in the field of energy harvesting. Energy harvester output power is the most important parameter in a vibration energy harvesting system. Assessing the harvester output power in different vibration environments is an important study issue to study. LÄS MER
