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.

Systems and methods for long-distance remote sensing with sub-wavelength resolution using a wirelessly-powered sensor tag array

Wirelessly powered receiver system and sensors are described. In an embodiment, the power receiver system, includes an inductive coil that receives wireless power from an external transmitter, a capacitor bank that optimizes power transfer to an energy harvesting device, and a power-receiving frontend RF-DC rectifier with a periodically enabled closed feedback loop that adapts settings of the capacitor bank in real-time to adapt to changes on the inductive coil to maximize power transfer efficiency.
