Dynamic Resonant Circuits for Wireless Chemical and Physical Sensing with a Reader and RFID Tags
A tag for detecting an analyte can include a radio frequency identification tag including a sensor portion, the sensor portion configured to change resistivity when the radio frequency identification tag contacts or interacts with an analyte, whereby the resistivity change alters an output of the radio frequency identification tag, wherein the sensor portion includes a circuit, and wherein the sensor portion is configured to activate the circuit or deactivate the circuit when contacted or having interacted with the analyte, where the sensor portion includes a plurality of carbon nanotubes associated with a chemically-degradable polymer. In certain embodiments, the chemically degradable polymer can be a metallo-supramolecular polymer.
