  1. 11. Application demonstrator for green IoT unit including Ligna S-power

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Arvid Bläser; [2022]
    Nyckelord :Ligna; Energy; IoT; Battery; Printed; Electronics; Harvester; LoRa; LoRaWAN;

    Sammanfattning : Ligna Energy has developed a printable battery, called S-Power. It is based on research in organic electronics. In order to demonstrate the functionality of the new batteries, an IoT device was developed. The demonstrator consisted of a Sensor for temperature and relative humidity (RH), LoRWAN communication and a circuit for energy harvesting. LÄS MER

    Nyckelord :Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Sammanfattning : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. LÄS MER

  5. 14. FAS : Framtidens potenta hjulupphängning

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Marcus Dahlström; Adam Mellin; [2022]
    Nyckelord :;

    Sammanfattning : The purpose of the project was to explore potential markets where EMTW can implement their patented adaptive suspension. The project team thus began to understand the functions of the adaptive suspension and how to utilize it. LÄS MER

  7. 15. Improving visual comfort and energy efficiency in a classroom : A comparative approach of evaluating a lighting design technique and a sensor positioning method

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik
