1. A method of detecting a stimulus comprising detecting an output from a radio frequency device having a circuit and including a sensor portion and a chemiresponsive sensor material, the chemiresponsive sensor material closing the circuit, the sensor portion configured to change a detectable property of the circuitry when the stimulus contacts or interacts with the radio frequency device, wherein the detectable property change alters the output of the radio frequency device.
