  1. 1. Design and implementation of an energy harvesting system in a prosthetic limb

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ódinn K. Rúnarsson; [2023]
    Keywords : Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oskar Nordström; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tomas Lorenzo Henriques Vazquez; [2022]
    Keywords : Energy harvesting; Vibration energy harvesting; Energy neutral; Internet of Things; Autonomous systems; Power management; Low Power Wide Area Networks; LTE-M; NB-IoT; Energiskördning; Vibrationsenergiskörd; Energineutral; Sakernas internet; Autonoma system; Energihantering; Lågenerginätverk med lång räckvidd; LTE-M; NB-IoT;

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

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

    Abstract : 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. READ MORE
