  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

  3. 2. Design Guidelines of A Low Power Communication Protocol for Zero Energy Devices

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

    Författare :Jiayue Zhang; [2023]
    Nyckelord :Energy efficient communication protocol; sensor data transfer; zero energy devices; battery-less; energy harvesting; Energieffektiv kommunikationsprotokoll; sensordatöverföring; “zero” energienheter; batterifria; energy harvesting;

    Sammanfattning : Lågströmskommunikationsprotokoll såsom 6LoWPAN har använts i stor utsträckning för applikationer som kräver mindre energiförbrukning för trådlös kommunikation på korta avstånd, exempelvis IoT-enheter. Eftersom antalet sådana enheter ökar blir det allt viktigare att överväga ambient energy harvesting som en energikälla för att driva sådana enheter. LÄS MER

  4. 3. 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
