   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

4. 3. Wireless Power Transfer : Machine Learning Assisted Characteristics Prediction for Effective Wireless Power Transfer Systems

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Shamsul Arefeen Al Mahmud; [2020]
   Nyckelord :Wireless power transfer; Machine learning; Coupling strength estimation; Load impedance estimation; Multi-transmitter wireless power transfer systems; Trådlös kraftöverföring; maskininlärning; uppskattning av kopplingsstyrka; uppskattning av belastningsimpedans; Multisändare trådlösa kraftöverföringssystem;

   Sammanfattning : One of the main challenges in wireless power transfer (WPT) devices is performance degradation when the receiver’s position and characteristics vary. The variations in the system parameters such as load impedance and coupling strength in WPT devices affect performance characteristics such as output voltage and power. LÄS MER

5. 4. Rapid Energy Transfer to an Energy Buffer

   Master-uppsats, KTH/Kommunikationssystem, CoS

   Författare :Claudia Muñiz García; [2007]
   Nyckelord :Rapid; Energy; Transfer; Buffering; Near Inductive Field;

   Sammanfattning : This master thesis introduces a new technology applicable to nearly all mobile and portable electrical devices since all of them need energy to operate. This thesis attempts to cut the last wire - this one the wire to the primary power source. LÄS MER
