  1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

  3. 2. Power-sourced charging over PoE to enable high power peaks

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Deshane Devis; Babak Abedpour; [2023]
    Nyckelord :;

    Sammanfattning : In contrast with well-known traditional Closed Circuit Television cam-eras, nowadays most electronic devices including Internet Protocol surveil-lance cameras , Wireless Access Point, Network Routers, Voice over Internet Protocol technologies ,and so forth are all powered throughPower over Ethernet cables. These cables are capable of delivering bothDirect Current power and data simultaneously using a single main cable for the Local area network, this tremendously assisted system integra-tors and network installers to deploy electronic devices in locations that lack electrical circuitry and eventually eliminating the extra expensesof installing additional electrical wiring as well as power supplies.
