1. 1. Energy harvesting of ambient radio waves

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datorteknik

   Författare :Patrik Starck; [2018]
   Nyckelord :ambient radio waves energy harvesting;

   Sammanfattning : The aim for this thesis was to investigate if harvesting of ambient radio waves could be a viable source of energy and where and when it can be used. A survey of the signal strengths at different locations in Uppsala, Sweden was performed which showed that the cellular frequency bands were the ones that carried the most energy. LÄS MER

   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
