Abstract
In some embodiments, an apparatus includes an antenna; a radio-frequency (RF) tuning network configured to receive an input signal via the antenna; an RF energy harvester operatively coupled to the RF tuning network and configured to produce a direct current (DC) output based on the received output of the RF tuning network; and a load manipulator configured to be transitioned between a first configuration and a second configuration to manipulate one or more properties associated with the RF energy harvester such that an input impedance of the RF energy harvester changes from a first input impedance to a second input impedance. The first input impedance is associated with a first distribution of RF energy associated with the input signal relative to the RF energy harvester and the second input impedance is associated with a second distribution of RF energy associated with the input signal relative to the RF energy harvester.
