  1. 16. 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

  3. 17. Fire Detection System using Infrared Sensor and Camera

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

    Author : Kristoffer Burghardt; Martin Forslund; [2022]
    Keywords : Infrared Sensor; Fire; Fire Detection; Sensor Based Systems; Wireless Communication; Infraröd Sensor; Eld; Elddetektering; Sensor Baserade System; Trådlös Kommunikation;

    Abstract : The last decades has seen the rise of digitization and automation of certain tasks at dangerous work environments though this has not yet affected the firefighting profession. With sensors and remote vehicles it is possible to aid the firefighters in analyzing a situation and aid them in the extinguishing efforts which reduces risks and time spent finding the fires.

  4. 18. Ultra-wideband location tracking of mobile devices

    University essay from Uppsala universitet/Signaler och system

    Author : Daniel Hietarinta; [2022]
    Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

    Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

  5. 19. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

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

    Author : Ibrahim Hamed; [2022]
    Keywords : Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

    Abstract : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.
