Abstract:

Far field wireless power transfer (WPT) enabled Internet-of-Things (IoT) applications are the emerging technology and the future trend along with the rapid development of 5G IoT ecosystems. WPT-enabled IoT devices enjoy many advantages as battery-free, environmental-friendly, capable of operating in remote places without manual maintenance.

This talk will introduce the history and development of WPT technology at the beginning, and will be followed by a series of advanced antenna technologies for far field WPT-enabled battery-free IoT systems. Several metamaterial-inspired electrically small rectennas with exceptional wireless power capture capacities will be introduced. Based on the developed ultra-compact rectennas, two WPT-enabled light and temperature sensor systems have been successfully built and tested. A video demo of the prototyped system will be presented. Moreover, an ultrathin beam-steerable transmitting antenna with long distance and larger area coverage will be discussed.
