RFID markers and systems and methods for identifying and locating them
Systems and methods are provided for identifying or locating a tag within a patient's body that include a probe that transmits synchronized electromagnetic signals, e.g., RF energy, and optical signals, e.g., infrared light pulses into the patient's body, whereupon the tag converts the optical signals into electrical energy to open and close a switch in the tag to modulate signals, e.g., backscatter signals, transmitted by the tag in response to the electromagnetic signals. For example, the tag may include photodiodes coupled to the switch that transforms the optical signals to alternately short the antenna to modulate the backscatter signals. Alternatively, the tag may include a smart circuit that harvests electrical energy from the optical signals to power the smart circuit and/or modulate the backscatter signals, e.g., to include data related to the tag and/or alternate the tag between an information mode and a distance mode.
