    Sammanfattning : The human body possesses a highly developed range of senses that help orienting oneself in everyday life. Especially when it comes to navigating, perceiving and reacting to the world around us, people tend to rely mostly on their vision and hearing. LÄS MER

  3. 2. Thermal energy harvesting for indoor industrial applications

    Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Mengxuan Li; [2017]
    Nyckelord :Thermal energy harvester; thermal energy generator; temperature difference; air flow; heat sink; comsol multiphysics;

    Sammanfattning : Wireless sensor network (WSN) nodes cannot directly used by the traditional power grid, a most common way to supply power to WSN nodes is to use batteries. However, the battery has a disadvantage that is the limited lifetime, adding an energy harvester to extend the lifetime is a good way. LÄS MER

  7. 5. Peltierelement - spillvärme till el : Peltier element - waste heat into electricity

    Uppsats för yrkesexamina på grundnivå, Elektricitetslära

    Författare :Elisabet Hansson; [2012]
    Nyckelord :Peltierelement; termoelektrisk kylare; TEC; termoelektrisk generator; TEG; spillvärme; elgenerering;

    Sammanfattning : The purpose of this thesis has been to determine experimentally how good a peltier element is to convert waste heat from wood burning. Three different peltier elements were used in a comparison study. The comparison was mainly done to know how much power could be obtained from each element. LÄS MER
