US 2022/0264196 A1 · Systems and Methods for Long-Distance Remote Sensing With Sub-Wavelength Resolution Using a Wirelessly-Powered Sensor Tag Array

Abstract

Systems and methods for remote sensing are described. In an embodiment, an apparatus, includes: a radio frequency identification (RFID) tag; an electromagnetic transmitter configured to emit electromagnetic waves; an ultra-wideband (UWB) receiver; a computer system; where: the RFID tag is configured to be operated without a battery, and to be powered by the electromagnetic waves emitted by the electromagnetic transmitter; where the RFID tag is configured to send out UWB impulses based on an amount of electromagnetic power received from the electromagnetic transmitter, such that a repetition rate of the UWB impulses varies with the amount of electromagnetic power received from the electromagnetic transmitter
