Journal ArticleDOI
Analysis, Experimental Results, and Range Adaptation of Magnetically Coupled Resonators for Wireless Power Transfer
TL;DR: A circuit model is presented along with a derivation of key system concepts, such as frequency splitting, the maximum operating distance (critical coupling), and the behavior of the system as it becomes undercoupled, including the introduction of key figures of merit.
Journal ArticleDOI
Design of an RFID-Based Battery-Free Programmable Sensing Platform
TL;DR: To the authors' knowledge, WISP is the first fully programmable computing platform that can operate using power transmitted from a long-range (UHF) RFID reader and communicate arbitrary multibit data in a single response packet.
Patent
Wireless power transfer apparatus and method thereof
TL;DR: In this article, a method and apparatus that includes features of a receiving antenna configured to wirelessly receive power transmitted by a transmitting device and arranged to associate or dissociate with the transmitting device is described.
Proceedings ArticleDOI
Experimental results with two wireless power transfer systems
TL;DR: The first system harvests VHF or UHF energy from TV towers, with power available depending on range and broadcast transmit power, and is described on an experiment in which 60uW is harvested at a range of about 4km.
Journal ArticleDOI
Enabling Seamless Wireless Power Delivery in Dynamic Environments
TL;DR: An overview of methods used to adapt to variations in range, orientation, and load using both wideband and fixed-frequency techniques is provided.
