  1. 1. Active Infrared light power supply for indoor wireless sensor nodes

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Jialei Chen; [2020]
    Nyckelord :Energy Harvesting; IR; WSN; Photovoltaic;

    Sammanfattning : In order to expand the energy source in energy harvesting, this thesis explores the feasibility of using infrared light source as the energy source. Firstly, the thesis investigated the current energy harvesting solution and the way of using infrared light energy, and determined the use of crystalline solar panels as energy harvesters. LÄS MER

  3. 2. 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

  4. 3. Development of an automated space rated solar panel array for future lunar rover mission

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

    Nyckelord :;

    Sammanfattning : Space industry has been enormously growing in the last decades. Energy harvestingfor space applications is usually a critical aspect of space missions, andtherefore a method for doing it is included in most of the satellites and vehiclessent to space. This project focuses on energy harvesting for a Moon Rover. LÄS MER

  5. 4. Comparison between Active and Passive AC-DC Converters For Low Power Electromagnetic Self-Powering Systems : A theoretical and experimental study of low power AC-DC converters

    Kandidat-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Ibrahim Hamed; [2020]
    Nyckelord :Energy-harvesting; electromagnetic; rectifiers; AC DC-converters; Active voltage doublers; Passive voltage doublers.;

    Sammanfattning : Electromagnetic based energy harvesting systems such as Variable reluctance energy harvesting systems (VREH) have shown to be an effective way of extracting the energy of rotating parts. The transducer can provide enough power to run an electronic sensing system, but the problem arises in finding an efficient way of rectifying that power to generate a stable energy supply to run a system, which this report will investigate.

  7. 5. Energialstring för drivande av smart enhet utan batterier : Design av ett energialstrande system för smart sko genom piezoelektronik och solceller

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Clive Rudd; [2019]
    Nyckelord :PCB; smart shoes; energy harvest; piezoelectronics; supercapacitors; solar cells; Kretskort; smart sko; energialstring; piezoelektronik; superkondensatorer; solceller;

    Sammanfattning : Projektet beskriver ett tillvägagångssätt för att alstra energi genom solceller och piezoelektronik. Ett kretskortsbaserat system designades som utnyttjade superkondensatorer som lagringsenhet. Planen var att integrera systemet i en sko. LÄS MER
